Question

6(x - 2) = 6 - 4x + 9x

Explanation:

Step1: Expand left-hand side

$6(x-2) = 6x - 12$

Step2: Simplify right-hand side

$6 - 4x + 9x = 6 + 5x$

Step3: Isolate x terms (subtract 5x)

$6x - 12 - 5x = 6 + 5x - 5x$
$x - 12 = 6$

Step4: Isolate x (add 12)

$x - 12 + 12 = 6 + 12$

Answer:

$x = 18$
