2x + 10 = 3 (x + 4) - x

2x+10 = 3x+12-x

10-12=3x-x-2x

2 = x

x=2

2x + 10 = 3 (x + 4) - x

Multiply the number outside the parenthesis with the numbers/variables inside the parenthesis

2x + 10 = 3x + 12 - x

Subtract 10 from both sides

2x = 3x + 2 - x

Add x to both sides

3x = 3x + 2

Subtract 3x from both sides

Final Answer: x=2
