The y-value of the solution to the system of linear equations given is: A. -4.
How to Find the Solution to the System of Linear Equations?
Given two linear equations, such as:
4x + 5y = −12 --> Eqn. 1
-2x + 3y = −16 --> Eqn. 2
Multiply eqn. 1 by 2 and eqn. 2 by 4
8x + 10y = −24 --> Eqn. 3
-8x + 12y = −64 --> Eqn. 4
Add to eliminate x
22y = -88
22y/22 = -88/22
y = -4
The y-value of the solution is: A. -4.
