First step is simplifying both sides of the equation.
-8 + (3) (9y) = 8 - 9 - 7y + 299
-8 + 27y = - 7y + (8 - 9 + 299)
Then, combine like terms.
-8 + 27y = - 7y + 298
Add 7y to both sides which turns 27y to 34y and gets rid of the 7y on the right side.
-8 + 34y = 298
Add 8 to both sides.
34y = 306
Divide both sides by 34.
34y/34 = 306/34
