Single and Two Step Equations

x + 7=12

• x=19
• x=-7
• x=5
• x=12

16 = p - 3

• p=19
• p=-19
• p=-13
• p= 13

  m - (-3) = 11

• -13
• 14
• 8
• -8

In the equation
4p = 20
 the variable, p, is being multiplied by 4. How should you show your work to isolate the variable and solve the equation?

• Multiply both sides by 4.
  The solution is x = 80.
• Subtract 4 from both sides. 
  The solution is p = 16.
• Add 4 to both sides. The solution is p = 24.
• Divide both sides by 4. The solution is p = 5.

y - 4.6 = 12

• 16.6
• 5.8
• 7.4
• Answer not Given

2x + 16 = 130

• x=114
• x=57
• x=-114
• x=-57

The goal of solving two-step equations is to:

• Move the constant
• Find the coefficient 
• Find the value of the variable
• Combine like terms

The steps in solving 5b - 6 = 24 are:
