Question

b. $4x - 6 = 4x + 3$

Explanation:

Step1: Subtract $4x$ from both sides

$4x - 6 - 4x = 4x + 3 - 4x$

Step2: Simplify both sides

$-6 = 3$

Step3: Analyze the resulting statement

This is a false contradiction, so no $x$ satisfies the equation.

Answer:

No solution (the equation is a contradiction)
