In parallelogram ABCD, opposite sides are congruent, it means AB = CD BC = AD So, 3y – 6 = 2y + 4 ........1 and 5x – 8 = 4x –1...........2 now we can find the value of x and y from expression 1 and 2, 3y – 6 = 2y + 4 3y-2y = 4+6 y = 10 5x – 8 = 4x –1 5x-4x = -1+8 x = 7 Thus, the value of x is 7, option A is the correct.
