x = -1, y = 1
Step-by-step explanation:
Given that:

Isolate x for 4x + 11y = 7 which ⇒ 
Substitute  into the equation: which is:
 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

If the traslation is T(x,y)=(x-1,y+1) then:

Therefore A'=( -7,3).
