Question

The equations in this system were added to solve for y. What is the value of y?

Answer 1

Answer:

The value of y is -5/9.

Step-by-step explanation:

The system of equations is:

$x+6y=10\\-x+3y=-15$

Add the two equations and solve for y as follows:

x + 6y =  10

-x + 3y = -15

_________

      9y = -5

        y = -5/9

Thus, the value of y is -5/9.
