What you need to do is solve this with system of equations. So since you already have y=2x-3, you need to get 2y= x+3 to just y=mx+b form. Once you get y=mx+b form, you have two equations of y=2x-3 and y=1/2x+3 then you use system of equations to solve for x. After you solve for x you get x to equal 4. Then you plug 4 into the x spots to find what y is. Y=5 and X=4
