Question

what is y?
2(-3y-6)+4(5y-8)=92
I got 9.5 but when I checked it, I couldn't seem to get the right one.

Answer 1

2(-3y - 6) + 4(5y - 8) = 92    |use distributive property: a(b - c) = ab - ac

-6y - 12 + 20y - 32 = 92

14y - 44 = 92    |add 44 to both sides

14y = 136    |divide both sides by 14

y = 136/14

y = 68/7

y = 9 5/7
