3. if on = 5x - 7, lm = 4x +4, nm = x - 7, and ol = 3y – 4, find the values of x and y for which lmno must
be a parallelogram. the diagram is not to scale.
n ch-7=5x

x = 11 and

Step-by-step explanation:

If LMNO is a parallelogram then it's opposite sides will be equal.

So, LM = ON

⇒ 4x + 4 = 5x - 7

⇒ x = 11

Now, MN = OL  

⇒ x - 7 = 3y - 4

⇒ 11 - 7 = 3y - 4 {Since we already have, x = 11}
