Question

Does anyone know this?

what is the solution of the equation. Find the value of y when x equals 1 9x+7y= -12

Answer 1

-3

Explanation:

Since x=1, we can simplify the equation to 9+7y=-12.

To find the value of 7y, we first have to find what is missing.

-12-9=-21, so 7y has to be equal to -21. -21/7 equals -3, so y=-3.
