You want to try eliminate one of the two variables (either x or y). When you do this, you're able to for one variable, plug that value in the equation and solve for the other variable.

Help, Can anyone show me how to do the formula to solve these equations?
4x-5y=38
7x-8y=-22
If you can show me the right way to solve, I do not understand how to get the answer.
