one way i solve them is first i add or subtract whatever was done to the constant+variable(4t). then i solve it. after i have solved it i either divide or multioly depending on the sign. i solve the equation after i finished this. i use the calculator to check my answer
here is an example
54x+72/45=12
54x+72/45-72/45=12-72/45
54x=10.4
54x/54=10.4/54
x~0.2
~ this symbol means about
i dont get it,it post to show something like this
x+(-5/4)=-10 1\4?

How are solving equations similar to solving inequalities?
Solving equations and inequalities both involve finding the values of variables that satisfy a given mathematical statement. In both cases, you apply similar algebraic techniques, such as adding, subtracting, multiplying, or dividing both sides of the equation or inequality. However, while equations have a specific solution, inequalities can have a range of solutions. Additionally, when multiplying or dividing by a negative number in inequalities, the direction of the inequality sign must be reversed, which is a key difference from solving equations.
How is multiplying and dividing related?
Multiplying and dividing are inverse operations in mathematics, meaning they are essentially opposite processes. When you multiply a number by another, you are increasing it by that factor, while dividing a number by another reduces it to a fraction of the original. For example, if you multiply 4 by 2 to get 8, dividing 8 by 2 returns you to 4. This relationship helps in solving equations and understanding the properties of numbers more effectively.
What does the first unit of algebra cover?
It depends on the edition, but typically, it would include, working with expressions that include variables - for example, adding, subtracting, multiplying, and dividing such expressions; fractions (also with expressions); writing equations (based on word problems) and solving those equations; factoring polynomials; graphing; perhaps some basic trigonometry. - High school algebra is all about working with variables.
What is the key to solving 2-step equations?
The key to solving 2-step equations is to isolate the variable by performing inverse operations in the correct order. First, eliminate any constant term by adding or subtracting it from both sides of the equation. Next, address the coefficient of the variable by multiplying or dividing both sides accordingly. Always ensure to maintain balance in the equation throughout the process.
How does solving equations compare and contrast to solving inequalities?
Solving equations involves finding specific values that satisfy a mathematical statement, where both sides are equal. In contrast, solving inequalities determines ranges of values that satisfy a condition, resulting in solutions that can be expressed as intervals or sets. While both processes require similar algebraic techniques, inequalities introduce additional considerations, such as reversing the inequality sign when multiplying or dividing by a negative number. Ultimately, equations yield exact solutions, whereas inequalities provide a spectrum of possible solutions.
What is the Difference between solving equations and inequalities?
When solving an equation, you are looking for a specific answer or answers. However, when solving inequalities, you are only looking for what an answer could be (for example, your answer could be less than 5 or greater than 32).
How are solving inequalities differ from solving equations?
Mainly, in the case of simple inequalities, you have to remember that when multiplying or dividing by a negative number, the direction of the inequality changes, for example, from greater-than to less-than or vice versa. Also, for more complicated inequalities, such as those that involve polynomials or absolute values, additional steps are required.
Why is it essential to use balance equations in solving stoichiometric problems?
It is essential to use balanced equations when solving stoichiometric problems because each kind of atom has to be the same on both sides of the equation. The chemical reactions that take place are molar ratios.
