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

Explanation:

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#
