In the equation

x + 7 = 12

7 is being added to the variable, x. How should you show your work to isolate the variable and solve the equation?

• Subtract 7 from both sides.

• Subtract 12 from both sides

• Multiply both sides by 7

• Add 12 to both sides

Solve the equation: 
x + 7 = 12

• x = 5
• x = 19
• x = -5
• x = 84

Solve the equation:
x - 4 = -3

• x = -7
• x = 1
• x = 12
• x = -12

Solve the equation:
x - 3 = -12

• x = 9 
• x = -15
• x = -9
• x = 15

Solve the equation:
x - 4 = 6

• x = 10
• x = -10
• x = 2
• x = -2

Solve the equation:
4p = 16

• p = 12
• p = -12
• p = -4
• p = 4

Solve the equation:
x/-3 = -4

• x = 12
• x = 1
• x = -1
• x = -12

Solve the equation:
-5x = 25

• x = 20
• x = -20
• x = -5
• x = 5
