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.

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.

When you do this, you're able to ^solve* for one variable, plug that value in the equation and solve for the other variable.
