Solving One-Step Equations

Solve the following equation
X + 8 = 15

• 23
• -7
• 7
• -23

Solve the following equation
18 = 3b

• 15
• 6
• 21
• 54

Solve the equation:
x - 3 = -12

• x = 9 
• x = -15
• x = -9
• x = 15

Solve for x:

• x = 20
• x = 7
• x = 10
• x = 3

What is the correct step to solve for the variable?
15 = m - 5

• add 15 to both sides
• add 5 to both sides
• subtract 15 from both sides
• subtract 5 from both sides

What step would you have to take to solve the following equation?

9x=153

• multiply by 9 on both sides

• divide by 9 on both sides

• add 9 to both sides

• subtract 9 from both sides

Solve the equation:
-5x = 25

• x = 20
• x = -20
• x = -5
• x = 5

The objective when solving an equation is to....

• isolate the variable.
• check the solution.
• guess and check.
• Combine Like Terms.

Solve the equation
3x = 27. 

• x = 24
• x = 81
• x = 9

 $Solve\ the\ equation.\ \ \ \ \ \ \ \frac{1}{3}x=-12$  

• x = -4

• x = -36

• x = 4

• x = 36
