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

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.

Solve the equation
3x = 27. 

• x = 24
• x = 81
• x = 9

Which choice models this situation? Marcus needs to sell 25 tickets to a fundraiser by Friday. So far, he has sold 9 tickets. How many tickets does he still need to sell?

• t - 9 = 25

• t + 9 = 25

• 9t = 25

• t/9 = 25
