simplify: 9y+-3=24
reorder the terms: -3+9y=24
solve: -3+9y=24
you are solving for variable y
move all the terms containing y to the left, all others to the right.
add 3 to each side of the equation: -3+3+9y=24+3
combine like terms:
-3+3=ø
ø+9y=24+3
9y=24+3
combine like terms: 24+3=27, 9y=27
divide each side by 9: y=3
answer: y=3
hope this helps :)
