Divide each side of the equation by $-3$ to isolate $y$ while keeping the equation balanced. See below:

Divide each side of the equation by $color(red)(-3)$ to isolate $y$ while keeping the equation balanced.

$(-3y)/color(red)(-3) = (2x - 9)/color(red)(-3)$

$(color(red)(cancel(color(black)(-3)))y)/cancel(color(red)(-3)) = (2x)/color(red)(-3) - 9/color(red)(-3)$

$y = -2/3x + 9/3$

$y = -2/3x + 3$

How do you solve for y in -3y=2x-9-3y=2x-9?
