Question

6(2x - 1) - 4 = 2x + 20

Explanation:

Step1: Expand the left side

$6(2x - 1) - 4 = 12x - 6 - 4$

Step2: Simplify the left side

$12x - 6 - 4 = 12x - 10$

Step3: Rearrange terms to isolate $x$

$12x - 2x = 20 + 10$

Step4: Simplify both sides

$10x = 30$

Step5: Solve for $x$

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

Answer:

$x = 3$
