Find x and each side.

7x-8

3x16

As it is a parallelogram, Opposite sides are similar.

Sol.

7x - 8 = 3x + 16

➤7x - 3x = 16 + 8

➤4x = 24

➤x = 6

1) 7x - 8

= 7(6) - 8

= 42 - 8 = 34

Sides = 34

2) 3x + 16

= 3(6) + 16

= 18 + 16 = 34

Sides = 34

So the both problem is

equal to 34.

Hope it helps
