Answer:
x = -1, y = 1
Step-by-step explanation:
Given that:
Isolate x for 4x + 11y = 7 which ⇒ 
Substitute into the equation: which is:
Drop Down to:
Isolate y for 7-8y = -1: y = 1
Thus,
Substitute y = 1
Hence,
Solution ⇒ x = -1 and y = 1

Step-by-step explanation:
side ratio = big/small = 28/4 = 7
perimeter ratio = side ratio = 7
-> perimeter ratio = big / small = big/34 = 7
-> big perimeter= 7*34 = 238
