What is the y-coordinate of the solution for the system of equations? {x-y=1227+3y=2x Enter your answer in the box.

the answer is

x-y=12

27+3y=2x equivalent to - 2x + 3y = - 27

x - y = 12

-2x + 3y = - 27

and 2x - 2y = 24 (multiplied by 2 the first equation)

-2x + 3y = - 27

2x-2x - 2y+3y=24-27

y = - 3

the y coordinate of the solution for the system is y = - 3
