X = 2y + 12 5x + 3y =-44

1 answer:

8 0

Answer:

(-4, -8)

Step-by-step explanation:

Note that x in terms of y is x = 2y + 12. Substitute 2y + 12 for x in the second equation:

5(2y + 12) + 3y = -44

10y + 60 + 3y = -44

Then 13y= -104, and y = -8

From the first equation we find x = 2(-8) + 12, or x = -16 + 12, or x = -4

Then the solution is (-4, -8)
