One step equations

Solve the equation
3x = 27. 

• x = 24
• x = 81
• x = 9

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. The solution is x = 5.
• Add 7 to both sides.
  The solution is x = 19.
• Multiply both sides by 7 The solution is x = 84.

y - 33 = 147

• y = 114
• y = 177
• y = 180
• Answer not Given

Which equation has w = 8 as the solution?

• 8w= 64
• 16w = 240
• 16 - w = 9
• 4 + w = 10

Solve the following equation
X + 8 = 15

• 23
• -7
• 7
• -23

Solve the following equation
2y = 18

• 36
• 16
• 9
• 20

What would be the best first step to solving the equation?
-3=x+5

• add 3 to both sides
• subtract 5 from both sides
• add 5 to both sides
• subtract -5 from both sides

-6x = 30

• x = - 5

• x = 24

• x = 5

• x = 36

To Solve the Equation Below, you'd
x - 62 = 123

• add 62 to each side
• subtract 62 from each side
• multiply each side by 62
• Add 123 to each side

What is your first step when you solve  x + 5 = 12

• Add 5 to 5 and add 5 to 5 to 12
• Subtract 5 from 5 and subtract 5 from 12
• Subtract 12 from 12 and subtract 12 from 5
• Add 12 to 12 and add 12 to 5
