1. Solving basic equations
x + 14 = 34
- 14 = -14
x= 20
Step one: Subtract 14 from both sides.
Step two: bring down the x
x=20
Practice
X + 16 = X+24= x+34=84

2. Solving basic equations
x - 20 = 34
+20 = +20
x= 54
Step one: Add 20 to both sides.
Step two: bring down the x
x=54
Practice
X - 16 = X-24= x-34=14

3. Solving basic 2 step equations
3x - 20 = 34
+20 = +20
3x= 54
Step one: Add 20 to both sides.
Step two: bring down the 3x
Step Three: divide both sides by 3
X= 18
Practice
4X + 16 = X-25= x-34=14

4. Practice: solving basic equations
X + 45 = x + 9= x + 14= 28
2x + 45 = x-7= x- 40= 125
3x-12= x-12= x+12=36

5. Warm Up 4/12
Solve for X.
X + 4 = 24
X-12=8
X+7=28
4X=28
5X=60
