Answer:

How do you solve for multiple unknown variables?

Trying to solve two equations each with the same two unknown variables? Take one of the equations and solve it for one of the variables. Then plug that into the other equation and solve for the variable. Plug that value into either equation to get the value for the other variable.

What does it mean to solve for the unknown?

Algebra is about solving for unknowns. You use other information from your problem to setup an equation with the unknown. The unknown is called a variable. In order to solve for a variable (like x), you need to isolate the variable.
