Solving One Step Equations With Models

Which choice models this situation? Anna participated in a read-a-thon. Mr. Cole pledged $4 per book and gave Anna $44. How many books did Anna read?

• b - 4 = 44

• b + 4 = 33

• 4b = 44

• b/4 = 44

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

• add 5 to both sides

• add 15 to both sides

• subtract 15 from both sides

• subtract 5 from both sides

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.
