Let's solve the given equation step by step:

7y - 4(3y + 5) = 2 - 3(4y - 9)

Expanding the terms inside the parentheses:

7y - 12y - 20 = 2 - 12y + 27

Combining like terms:

-5y - 20 = 2 - 12y + 27

Rearranging the equation to group the y terms on one side:

-5y + 12y = 2 + 27 + 20

7y = 49

Dividing by 7 on both sides:

y = 7

Therefore, the solution to the equation is y = 7.
