2 – 3(4 – 5y) = 3(y + 3) + 5
2 – 12 + 15y = 3y + 9 + 5
-10 + 15y = 3y + 14
12y = 24
y = 2, answer C

2 – 3(4 – 5y) = 3(y + 3) + 5
Distribute...
2 - 12 + 15y = 3y +9 + 5
Combine like terms...
-10 + 15y = 3y + 14
Move y to one side and constants to the other...
15 y - 3y = 14 +10
12 y = 24
Divide both side by 12 to solve for y...
y = 2, thus the answer is C!
Hope that helps! Good luck!
