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

Solve the following equation 
8 = m - 12

• 4
• 0.5
• 5.0
• 20

-16+ x= -15

• 2
• 0
• -1
• 1

18 + a = -50

• a = -950

• a = -68

• a = -32

• a = -50/19

5 = f - 2

• 4
• 7
• -3
• 2

Solve for x.

x - 8 = -5

• x = 13

• x = -13

• x = 3

• x = -3

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.

Which of the following is used to solve single step equations mathematically?

• substitution
• inverse operations
• frequency
• data analysis
