Best ResponseYou've already chosen the best response.0The second step is that we need to combine our terms, like terms. we see that we have 7y+2y so we add those two 36+6y = 7y+2y after we combine like terms we get the following below: 36+6y = 9y now we need to isolate y if we're going to solve for it and we do that by subtracting 6 y from both sides 36 = 9y6y 36 = 3y we divide both sides by 3 and we get 36/3 = y = 12 from this we get y = 12 now we need to plug this back into our equation to check it. That's how we know this is correct. 36 = 3(12) 36 = 36
