Question

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

Answer 1

Answer:The

the answer is -3

Explanation:

Answer 2

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
