Two Step Equation Problems

This year, there are a total of 357 students in 6th grade. On Tuesday, sixteen classes had x 6th graders in them. There were a total of 15 students absent that day.

This situation can be represented by the equation:

357 = 16x+15

What would be the FIRST step in solving this equation?

• Subtract 15 from both sides of the equation

• Divide by 16 on both sides of the equation

• Add 15 to both sides of the equation

• Multiply by 16 on both sides of the equation

Jackie bought 2 pairs of ballet shoes and a tutu from Dance Works. She remembered that tutu was $38 and that the total cost was $148. Which equation can be used to find b, the cost of each pair of ballet shoes?

• 148 = 2b + 38

• 148 = 2b + 55

• 148 = 38 + b

• 148 = 38b

• m=3

• m=-4

• m=-1

• All real numbers

• x=3

• x=2

• x=-2

• x=1

How would you solve each equation?

• add 4 to both sides of =

• x-4=12

• divide both sides of = by 4

• x+4=12

• subtract 4 from both sides of =

• multiply both sides of = by 4

• 4x=12

A taxi charge a base fee of $3, plus $1.50 for each mile traveled, x. Mr. Lewis rode in the taxi from his home to the airport and was charged $30. How many miles does Mr. Lewis live from the airport?

• 30 =1.50x + 3

  x = 18 miles

• 30 = 1.50x - 3

  x = 22 miles

• 30 = 3x + 1.50

  x = 9.5 miles

• 30 = 1.50x + 3

  x = 22 miles

• 30 = 1.50x - 3

  x = 18 miles
