Example 1
x + 7 = -10
Example 1
x + 7 = -10-7 -7
Example 1
x + 7 = -10-7 -7
Example 1
x + 7 = -10-7 -7
x = -17
Example 1
x + 7 = -10-7 -7
x = -17
Example 2
x – 12 = 6
Example 2
x – 12 = 6+ 12 +12
Example 2
x – 12 = 6+ 12 +12
x = 18
Example 2
x – 12 = 6+ 12 +12
x = 18
Example 3
7x = 49
Example 3
7x = 497 7
Example 3
7x = 497 7
x = 7
Example 3
7x = 497 7
x = 7
Example 4
x = -513
Example 4
x = -513
3 3
1x = -15
Example 4
x = -513
3 3
1x = -15
Example 4
x = -513
3 3
1x = -151 1 x = -15
Example 5
3x - 2 = 6
Example 5
3x - 2 = 6 + 2 +2
Example 5
3x - 2 = 6 + 2 +2
3x = 8
Example 5
3x - 2 = 6 + 2 +2
3x = 83 3
Example 5
3x - 2 = 6 + 2 +2
3x = 83 3 x = 8

Example 6
4 – 2x = -26
Example 6
4 – 2x = -26-4 -4
Example 6
4 – 2x = -26-4 -4 – 2x = -30
Example 6
4 – 2x = -26-4 -4 – 2x = -30 -2 -2
Example 6
4 – 2x = -26-4 -4 – 2x = -30 -2 -2
x = 15
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
