Solve the Equation

Solve the following
2x - 1 = 9

• x = 5

• x = 4

• x = -5

• x = -4

Solve the following
2x + 1 = 9

• x = 5

• x = 4

• x = -5

• x = -4

4x - 12 = 2x + 6

• x = 36

• x = -36

• x = -9

• x = 9

12x - 1= x + 8

• x = 11/9

• x = -11/9

• x = -9/11

• x = 9/11

Solve the equation:
-5x = 25

• x = 20

• x = -20

• x = -5

• x = 5

4x + 7 = 23

• x = 16

• x = 4

• x = 9

• x = 12
