x=9, y=18
First, solve for y by setting y+14 equal to 3y-22 because since it is a parallelogram, the diagonals are congruent. You should get 18 for y one you solve the equation.
Then, plug 18 into 2y+2 and set that equal to 4x+2 for the same reason as the part, then once you solve for x, you should get 9.
