Example question
3(x + 2) - 5 = 16
Work through it
- 1
3x + 6 - 5 = 16
Distribute 3 to both terms inside the parentheses.
- 2
3x + 1 = 16
Combine the constants 6 and -5 because they are like terms.
- 3
3x = 15, then x = 5
Subtract 1 from both sides, then divide both sides by 3 to isolate x.
Final answer
x = 5
