Question

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

X+6y- 10
- X+3y=-15
9y=-5​

Answer 1

B

Explanation:

-5/9

Answer 2

The value of y is -5/9.

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.
