1. ONE STEP EQUATIONS Addition and Subtraction

2. / / x + 6 - 6 - 6 x 2 = ONE STEP EQUATIONS Solve 6 + x = 8 x + 6 = 8
Commutative Property
x + 6 = 8
x + 6 = 8 x
+ 6 /
must also be done to the other side to keep it balanced.
What you do to one side of the equation /
- 6
- 6 x = 2

3. Check your answer!!!!!! 8 = 8 ONE STEP EQUATIONS 6 + x = 8 6 + 2 = 8
Rewrite original equation substituting our answer for x
Original equation
6 + x = 8
6 + 2 = 8
Does our answer make the equation true?
8 = 8
Yes 

4. / / x - 4 + 4 +4 x 24 = ONE STEP EQUATIONS Solve 20 = x - 4 x - 4 = 20
Symmetric Property
x - 4 = 20
x - 4 = 20 x
- 4 /
must also be done to the other side to keep it balanced.
What you do to one side of the equation
+ 4 / +4 x = 24

5. Check your answer!!!!!! 20 = 20 ONE STEP EQUATIONS 20 = x - 4
Rewrite original equation substituting our answer for x
20 = x - 4
Original equation
20 =
Does our answer make the equation true?
20 = 20
Yes 

6. REWRITE 3 + x = 11 10 = x - 2 x – 2 = 10 x + 3 = 11 12 = x + 7

7. ONE STEP EQUATIONS with Integers
Solve x – 4 = -5
x - 4 = -5 /
must also be done to the other side to keep it balanced.
What you do to one side of the equation
+ 4 / +4 x = -1

8. Check your answer!!!!!! -1 – 4 = -5 -5 = -5 ONE STEP EQUATIONS
Rewrite original equation substituting our answer for x
x – 4 = -5
Original equation
-1 – 4 = -5
Does our answer make the equation true?
-5 = -5
Yes 

9. ONE STEP EQUATIONS with Integers
Solve x + 8 = 5
x + 8 = 5 /
must also be done to the other side to keep it balanced.
What you do to one side of the equation /
- 8 -8 x = -3

10. Check your answer!!!!!! -3 + 8 = 5 5 = 5 ONE STEP EQUATIONS x + 8 = 5
Rewrite original equation substituting our answer for x
x + 8 = 5
Original equation
= 5
Does our answer make the equation true?
5 = 5
Yes 

11. ONE STEP EQUATIONS with Integers
Solve -2 = x + 5
x + 5 = -2 /
must also be done to the other side to keep it balanced.
What you do to one side of the equation /
- 5
- 5 x = -7

12. Check your answer!!!!!! -2 = -7 + 5 -2 = -2 ONE STEP EQUATIONS
Rewrite original equation substituting our answer for x
-2 = x + 5
Original equation
-2 =
