Question

solve for z. -7(2z - 18) = -16z z = submit

Explanation:

Step1: Expand left-hand side

$-7(2z - 18) = -14z + 126$
Equation becomes: $-14z + 126 = -16z$

Step2: Add $16z$ to both sides

$-14z + 16z + 126 = 0$
$2z + 126 = 0$

Step3: Subtract 126 from both sides

$2z = -126$

Step4: Divide by 2 to solve for z

$z = \frac{-126}{2}$

Answer:

$z = -63$
