Question

PLEASE HELP What is the y-value in the solution to this system of linear equations?

4x + 5y = -12
-23.4 3y=-16
-4 -2 2 5

Answer 1

-2.

Explanation:

4x + 5y = -12

-23.4x + 3y = -16

23.4[4x + 5y = -12]

4[-23.4x + 3y = -16]

93.6x + 117y = -280.8

-93.6x + 12y = -64

129y = -344.8

y = -2.672868217

That is about -2.

Hope this helps!
