How do i do thois problem?Please help.

Problem #1
solve the system by subtraction.
5x-3y=13
4x-3y=11






Subtract the lower equation's left and right terms from the upper equation's corresponding terms. The first step will get you this:
x = 2
Now that you know x, use either of the two equations, and substitute of x=2, to solve for y.
