Answer:

y = [tex]\bf~\frac{55}{-8}~or~-6,875[/tex]

Step-by-step explanation:

y - 3(3y - 7) = 76

y - 9y + 21 = 76 (here we get rid of the parenthesis)

y - 9y = 76 - 21 (here we take 21 to the other side of the equation)

y - 9y = 55 (here we subtract 76 - 21)

-8y = 55 (here we subtract y - 9y)

y = 55/-8 (here we take -8 to the other side of the equation)

y = [tex]\bf~\frac{55}{-8}~or~-6,875[/tex]

Answer:

[tex]y - 3(2y - 7) = 76 \\ y - 6y + 21 = 76 \\ - 5y = 55 \\ y = \frac{55}{( - 5)} \\ \boxed{y = - 11}[/tex]

-11 is the right answer.
