Example 7

4 = 3x - 9What if x is on the right side?

Example 7

4 = 3x - 9

What if x is on the right side?

Option 1: Leave it and solve Option 2: Switch it and solve

3x – 9 = 4

Example 7

4 = 3x - 9

The steps will be the same

Option 1: Leave it and solve Option 2: Switch it and solve

3x – 9 = 4+9 +9 +9 +9

Example 7

4 = 3x - 9

The steps will be the same

Option 1: Leave it and solve Option 2: Switch it and solve

3x – 9 = 4+9 +9 +9 +913= 3x 3x = 13

Example 7

4 = 3x - 9

The steps will be the same

Option 1: Leave it and solve Option 2: Switch it and solve

3x – 9 = 4+9 +9 +9 +913= 3x 3x = 13 3 3 33

Example 7

4 = 3x - 9

…and so will the answer

Option 1: Leave it and solve Option 2: Switch it and solve

3x – 9 = 4+9 +9 +9 +913= 3x 3x = 13 3 3 33

= x x =13 3
