You don't use unknown variables to solve an equation. The purpose of solving an equation is to find the value of the variable so that it's no longer unknown.
You find, or construct, an equation or set of equations which express the unknown variable in terms of other variables. Then you solve the equation(s), using algebra.You find, or construct, an equation or set of equations which express the unknown variable in terms of other variables.

The word "variable" represents an unknown number.
You use substitution when you can solve for one variable in terms of the others. By substituting, you remove one variable from the equation, which can then be solved. Once you solve for one variable, you can use substitution to find the other.
You plug in what the variable is equal to for that variable then you will be able to finish the problem
Equations are used to find the solution to the unknown variable.

Use a variable to represent the unknown. 'Translate' the words to math symbols and write an equation to solve. Solve the equation. Check.
All you do is set the quadratic function to equal to 0. Then you can either factor or use the quadratic formula to solve for your unknown variable.

There is no equation (nor inequality) in the question. There is also no unknown variable. So there is nothing to solve.
You use substitution when you can solve for one variable in terms of the others. By substituting, you remove one variable from the equation, which can then be solved. Once you solve for one variable, you can use substitution to find the other.

True. To solve a three variable system of equations you can use a combination of the elimination and substitution methods.
You use variable in math problems to help you solve the answer. For example, you could do 50+50=a. The (a) would be the variable. Or for that same problem you could do 50+y=100. Then the (y) would be the variable.
Usually in algebra the term "unknown" is used for a variable ( commonly designated as x ) you are trying to solve for. For instance the mathematical expression 2 + x = 5 may be presented to the student as a problem. The answer is to solve for the unknown or x. The solution would be x = 3
