x + 8 = 3 .

• x = 11

• x= 5

• x = -5

• x = -11

x - 3 = -2

• x = -5

• x = -1

• x = 5

• x = 1

10 = x + 15

• x = -5

• x = 5

• x = 25

• x = -25

• x =  -33

• x = 3.6

• x = -3.6

• x = 33

5y = -55

• y = 275

• y = -11

• y = 11

• y = -275

• x = 21

• x = 4

• x = -4

• x = -21

• Add 5 to both sides

• Subtract 15 on both sides

• Add 15 to both sides

• Divide by 5 on one side

• He subtracted 4 from each side.

• He divided both sides by -9.

• He added 4 to each side.

• He divided both sides by 4.
