so according to AIA (alternate interior angles are congruent) 4x+23 = 21y - 1 We also know that (4x+23)+(9x-38) = 180 because both of those make up a straight line (180 degrees)
darkknight:
First step would be using that second eqn to solving for x, then subing the value for x into the first eqn and solving for y

x=15?
darkknight:
yes. now step 2
