What is the y-coordinate of the solution for the system of equations?
2 answers:
Y= 12 - x
27 + 3( 12 - x ) = 2x
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!
