Answer:
1
Step-by-step explanation:
First equation is: x - y = 12
x = 12 + y
Now, substitute this in 2nd equation,
2x - 3y = 27
2(12+y) - 3y = 27
24 + 2y - 3y = 27
-y = 27 - 24
y = -3
In short, Your Answer would be -3
Hope this helps!

Answer:
2w + 3y - 1
Step-by-step explanation:
(2x+2)/y = 4w + 2
isolate x:
2x+2= y(4w + 2)
2x = y(4w + 2) - 2
x = y(2w + 1) - 1
x = 2wy + y - 1
x = 2w + 3y -1
