For a parallelogram, 3y+8 = 2x-4 and 5y = x+8

This is because the parallel sides are equal

3y + 8 = 2x-4 ..........(1)

5y = x+8...............(2)

from equation 2, y =(x+8)/5 .......(3)

substituting for y in equation (1) we have

3(x+8)/5 + 8 = 2x -4

3x+24 +(5x8) =5(2x-4)

3x+24 + 40 = 10x - 20

10x -3x = 40 +24+20

7x = 84

x = 12

From (2) , substituting for x yields

5y = x+8

5y = 12 +8

5y =20

y = 4
