Question

$x + 3 = 3(11 - 3x)$

Explanation:

Step1: Expand the right-hand side

$x + 3 = 3\times11 - 3\times3x$
$x + 3 = 33 - 9x$

Step2: Move x terms to left side

$x + 9x + 3 = 33$
$10x + 3 = 33$

Step3: Isolate constant terms on right

$10x = 33 - 3$
$10x = 30$

Step4: Solve for x

$x = \frac{30}{10}$

Answer:

$x = 3$
