x–3y=–9

Answer 1

To solve for y in the equation x - 3y = -9, we need to isolate y.

First, we can move the x to the other side of the equation by adding 3y to both sides:

x - 3y + 3y = -9 + 3y
x = 3y - 9

Next, we can divide by 3 to solve for y:

x/3 = y - 3
y = (x/3) + 3

Therefore, the solution for y in the equation x - 3y = -9 is y = (x/3) + 3.
