One solution means there is only one value or set of values for the variable(s) that satisfies the equation or system of equations. It is the point at which the graph of the equation intersects the x-axis, solving for the variable(s) in the equation.
The dependent variable is the rate of salt dissolution in the solution.
An independent variable is a variable that is manipulated or controlled by the researcher in an experiment to determine its effect on the dependent variable. It is the variable that is changed or varied to observe its impact on the outcome.
experiment
A manipulated variable, also known as an independent variable, is the variable that is intentionally changed or controlled by the experimenter in an experiment. Its purpose is to determine the effect it has on the dependent variable.
Substitute the value found back into the equation, evaluate the expressions and see if the resulting equation is true.
That's the "solution" of the equation.
The value of a variable is called the solution. You can determine if the solution is correct by solving for the variable by using the Distributive Property, and Inverse Operation. For an example: If x = 8, determine if it is a solution to 1x - 4 = 4 Replace x with 8. 1(8) - 4 = 4 1 * 8 = 8 8 - 4 = 4 4 = 4 Yes. 8 is a solution to the equation
The number that can replace a variable in an equation to make it a true equation is called the solution or root of the equation. This number satisfies the equation when substituted for the variable. In algebra, finding the solution involves solving for the variable by performing various operations to isolate it on one side of the equation. The solution is the value that balances both sides of the equation, making it true.
a solution
That's the "solution" to the equation described by the sentence.
Substitution

substitution
Isolating a single variable in terms of the rest of the equation provides a solution to that variable. That is, if you know the equation that equals the variable, then you can figure out its value.
Several methods exist. For example: solve one equation for one variable, replace that variable in the other equation. (Two simultaneous equations will often have two variables each.)
I'm going to assume you have an equation to go with your variable? It means "Check if this number works" What to do is put the given value into the equation instead of the variable and see if the result is true - if it is you have a solution, if not you don't. I'll make one up as a demo: Equation : a + 4 = 7 is a = 2 a solution? a+4=7 2+4=7 6=7 (FALSE!) No this given value is not a solution.
