solve for x and y
2x-9y=-23
8x-5y=1

Question

This looks like a great problem to do elimination in. Take your first equation and multiply it through by a constant which will allow you to vertically combine the two equations so that you are left with one variable. Once you've done that, you can plug in your answer to either of the two original equations to get the second variable's value.

It looks like the x coefficients will be easy to cancel out. (Hint: the constant you multiply through is going to be negative.)
