Question

What is 4(3q - 2) = 16q

Answer 1

$4(3q-2)=16q\\\\12q-8=16q\ \ \ \ \ \ |add\ 8\ to\ both\ sides\\\\12q=16q+8\ \ \ \ \ \ |subtract\ 16q\ from\ both\ sides\\\\-4q=8\ \ \ \ \ \ \ |divide\ both\ sides\ by\ (-4)\\\\\boxed{q=-2}$

Answer 2

$4\cdot (3q - 2) =16q$
We first multiply the expression in parentheses by 4:
$4\cdot 3q - 4\cdot 2 = 16q$
$12 q - 8 = 16 q$
Then, we move expression with q to the left hand side and constant to the right hand side:
$12q - 16q = 8$
$-4q = 8$
We divide both sides by (-2):
$q = -2$
