Answer:
y=13 , x=36
Step-by-step explanation:
The diagonal of parallelogram bisect at a point where the sides across the intersection are equal
DH=HF
x+3=3y
x=3y-3 first equation
HE=GH
2x-5=5y+2 ⇒ 2x-5y=7 second equation
solve by substitution: x=3y-3
2x-5y=7
2(3y-3)-5y=7
6y-6-5y=7
y=7+6
y=13
x=3y-3
x=3(13)-3
x=36
