Answer:
x = 11 , y = [tex]\frac{8}{3}[/tex]
Step-by-step explanation:
The opposite sides of a parallelogram are congruent
For the figure to be a parallelogram , then
ON = LM, that is
5x - 7 = 4x + 4 ( subtract 4x from both sides )
x - 7 = 4 ( add 7 to both sides )
x = 11
and
OL = NM , that is
3y - 4 = x - 7 = 11 - 7 = 4 ( add 4 to both sides )
3y = 8 ( divide both sides by 3 )
y = [tex]\frac{8}{3}[/tex]
