3(15 - x) = 2x (remove the parentheses)

45 - 3x = 2x (move the terms)

-3x - 2x = -45 (collect like terms)

-5x = -45 (divide both sides)

x = 9

Answer:

x = 9

Explanation:

Step 1: Write equation

3(15 - x) = 2x

Step 2: Solve for x

Distribute 3: 45 - 3x = 2x

Add 3x to both sides: 45 = 5x

Divide both sides by 5: x = 9

Step 3: Check

Plug in x to verify if it's a solution.

3(15 - 9) = 2(9)

3(6) = 18

18 = 18
