Answer:
(x= -7 , y = -1) is the complete solution of the equation.
Explanation:
The given equation is -7x - 5y = 54
Now, here substitute x = -7
So, we get
-7(-7) -5y = 54
or, 49 - 5y = 54
⇒ -5y = 54 - 49
or, -5y = 5
⇒ y = 5/(-5) = -1 , ⇒ y = -1
Hence, (x= -7 , y = -1) is the complete solution of the equation.
