Question

b. $24 + 3x = 3x + 3(7 - 1)$

Explanation:

Step1: Simplify right-hand side

First calculate the expression inside the parentheses, then multiply:
$3(7-1)=3\times6=18$, so the equation becomes $24 + 3x = 3x + 18$

Step2: Isolate variable terms

Subtract $3x$ from both sides:
$24 + 3x - 3x = 3x + 18 - 3x$

Step3: Simplify both sides

$24 = 18$

Answer:

This equation has no solution, as $24=18$ is a false statement.
