Answer 2

I can help you solve this equation. Here are the steps:

- First, we need to simplify the left side of the equation by using the distributive property. We multiply 9 by each term inside the parentheses and combine like terms. We get:

9⋅(2+y)−4y=6y−60 18+9y−4y=6y−60 14+5y=6y−60

- Next, we need to isolate y on one side of the equation by subtracting 5y from both sides and adding 60 to both sides. We get:

14+5y−5y=6y−60−5y 14+60=6y−5y−60 74=y

- Finally, we can check our answer by plugging in y=74 into the original equation and see if it is true. We get:

9⋅(2+74)−4⋅74=6⋅74−60 9⋅76−296=444−60 684−296=384 384=384

- Since both sides of the equation are equal, our answer is correct. Therefore, y=74 is the solution to the equation.
