Answer key · One-step equations
1. 3
Do the inverse of + 4: subtract 4 from both sides.
x = 7 − 4 = 3.
2. 4
Do the inverse of + 5: subtract 5 from both sides.
x = 9 − 5 = 4.
3. 2
Do the inverse of + 5: subtract 5 from both sides.
x = 7 − 5 = 2.
4. 5
Do the inverse of + 3: subtract 3 from both sides.
x = 8 − 3 = 5.
5. 2
Do the inverse of + 1: subtract 1 from both sides.
x = 3 − 1 = 2.
