What is a one-step equation?

• A problem where multiple operations are present.
• A problem where the variable is missing.
• An equation where only one step (operation) is needed to solve it.
• An equation where two steps (two operations) are needed to solve it.

Solve for x:

• x = 20
• x = 7
• x = 10
• x = 3

Figure out what n equals in this equation:
6n + 4 = -26

• n=-6
• n= -5
• n= 8
• n= -4

What is the first step in solving the equation?

• Add 4 to each side
• Subtract 4 from each side
• Subtract 2y from each side
• Divide each side by 2y

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.

36 = -10 + 2n

What is the SECOND step in

solving the equation above?

• Divide by 2 on each side.

• Subtract 10 from each side.

• Divide by -2 on each side.

• Add 10 to each side.
