Question

What is the x-value in the solution to the following system?
3x+9y=-18

Answer 1

(-18 - 9y) / 3.

Explanation:

To find the x-value in the solution to the system 3x+9y=-18, we can solve for x.

First, we subtract 9y from both sides of the equation to get:

3x = -18 - 9y

Then, we divide both sides by 3 to get:

x = (-18 - 9y) / 3

Therefore, the x-value in the solution to the system is (-18 - 9y) / 3.
