when you are given two equations which are both true,and you are asked to solve for both x and y.you plan to solve this set of equations by substituting part of one equation into the other so you end up with an equation that contains only x's or only y's .what is the first thing you need to do?

Solve one of the equations for x or y so you can substitute the result into the other equation.
