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:
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
