When you put the number in place of the variable (like maybe the 'x' or the 'y')
wherever the variable occurs in the equation, and the statement you get out of all
the numbers you have is not true, then you know the number is not a solution.
If this value a satisfy the equation, then a is a solution for that equation. ( or we can say that for the value a the equation is true)
An equation is equivalent to another equation, if they have the same solution.
not always but most of the time yes
plug your answer it to the original question
The number that replaces a variable is the solution to the equation. great question, but it's only the answer.??
The solution set is the answers that make an equation true. So I would call it the solution.
Substitute the number in the equation. If the resulting statement is true the number is a solution to the equation.
An equation has an equal sign, which means that we know what the variable is equal to :)
If this value a satisfy the equation, then a is a solution for that equation. ( or we can say that for the value a the equation is true)
Any number that makes an equation true is a 'solution of an equation'. it is a solution
A number that makes an equation true is its solution.
Solution. A solution of an equation is a number that satisfy the equation. This means that if you replace this number on the equation and check it, the equation will be true. When you solve an equation you can find some roots, but not all of them satisfy the equation. Thus always check your answers after resolving your equation, and eliminate as solution the answers that don't make the equation true or undefined.
An equation is equivalent to another equation, if they have the same solution.
An algebraic equation or inequality can have a solution, an algebraic expression cannot. If substituting a number in place of a variable results in the equation or inequality being a true statement, then that number is a solution of the equation or inequality.
Substitute the value found back into the equation, evaluate the expressions and see if the resulting equation is true.
The solution
" -7y plus 1975 " is not an equation, it doesn't ask any question, and it needs no solution. It's just an expression that stands for a number. There's no way to know what number it stands for until you know what number 'y' is.
