Answer:
QR = 5
Step-by-step explanation:
Since the parallelograms are similar, then the ratios of corresponding sides are equal, that is
= 
, then
= 
( cross- multiply )
9QR = 45 ( divide both sides by 9 )
QR = 5
4x+7y=47 /*4 ------>16x + 28y=188
5x-4y=-5 /*7 -------->35x-28y=-35
16x + 28y=188, add this two equations
35x-28y=-35
16x + 28y+35x-28y=188-35
16x +35x=188-35
51x =153m
x=3
5x-4y=-5
5*3-4y=-5
15-4y=-5
4y=15+5
4y=20
y=5
