Question

Pls help i have to find the mistake they made when he solved the equation

2(x + 3) = 6
2x + 3 = 6
- 3 - 3
2x = 3
+2 +2
x = 1.5

Answer 1

Mistake is 2x + 3 = 6. It should be 2x + 6 = 6. Therefore x = 0

Explanation:

2(x + 3) = 6

Expand the bracket:

2x + 6 = 6

Subtract 6 from both sides:

2x = 0

Divide both sides by 2

x = 0
