solution
or, 2 x + y = 5 y - 8 being opposite side of
parallelogram
or , 2x =5 y - y - 8
or, 2x = 4 y - 8
or, x = 4y - 8/2
or,. x = 2y- 4
therefore, 2x + y is equal to 5 y - 8 Being the opposite side of a parallelogram
now,
3y + 2 x is equal to 4x - 3 being opposite side of a parallelogram
or, 3y + 2 x-4x = -3
or,. 3y -2x = -3
