Algebra Equations Test Review

We want more math!

100

2x = 10 

x=5

200

x/2 + 1 = 10

   Subtract 1 from both sides:

   x/2 = 10 - 1

   x/2 = 9

   Multiply both sides by 2 to isolate x:

   x = 18

300

3+2x = 15

3+2x=15  

 2x=12

x=6

400

4x + 5 = 13

x=2

500

5x + 4 = 39

   x = 7

Math is so fun!

100

x - 1 = 10

x = 11

200

2x - 1 = 9

   Add 1 to both sides:

   2x = 9 + 1

   2x = 10

   Divide both sides by 2 to isolate x:

   x = 10 / 2

   x = 5

300

7x - 3 = 18

   x=3

400

2x - 1 = 3

 x=2

500

4x - 3 = 37

 x=10

Math is my favorite subject!

100

x/4 = 5

x=20

200

x/6 + 2 = 8

   Subtract 2 from both sides:

   x/6 = 8 - 2

   x/6 = 6

   Multiply both sides by 6 to isolate x:

   x = 6 * 6

   x = 36

300

2x + 1 = 45

   x=22

400

5x + 2 = 3x + 7

   Subtract 3x from both sides:

   2x + 2 = 7

   Subtract 2 from both sides:

   2x = 5

   Divide both sides by 2 to isolate x:

   x = 5 / 2

500

6x - 2 = 34

x=6

Math rules!

100

x + 5 = 10

x=5

200

x/7 - 3 = 12

   Add 3 to both sides:

   x/7 = 12 + 3

   x/7 = 15

   Multiply both sides by 7 to isolate x:

   x = 15 * 7

   x = 105

300

6x+2 = 20

x=3

400

3x + 6 = 27

   x=7

500

4x + 5 = 25

    x = 5
