Answer 2

Question:

$3(y - 1) = y - 11$

Answer:

$\boxed{y = - 4} \:$

Step-by-step explanation:

$3(y - 1) = y - 11$

$3y - 3 = y - 11$

$3y - y = - 11 + 3$

$2y = - 8$

$\boxed{y = - 4}$

Verification:

Substituting y = -4

$3(y - 1) = y - 11$

$3( - 4 - 1) = - 4 - 11$

$3( - 5) = - 15$

$- 15 = - 15$

Hence verified.
