Two Step Equation Word Problems Subtraction and Addition

331 students went on a field trip. Six buses were filled and 7 students traveled in cars. How many students were in each bus? Write an equation that matches this situation.

• 331=7x+6

• 331=13x

• 331=6x+7

• 331-7=6x

Penelope is going to the carnival to ride the rides. It costs $20 to get into the carnival and ride tickets are $0.50 each. Write an equation that represents this scenario if she spends $35 in all.

• .50x + 20 = 35

• .50x = 35

• .50 + 20x = 35 

• .50x - 20 = 35

A school is taking a trip to a museum. The fee for the bus is $85 and the museum charges a fee of $12 per student. The school paid a total of $613. Choose the equation to find out how many students went on the trip.

• 12s+ 85 = 613

• 85s + 12 = 613

• 85 - 12s = 613

Daniel is paid $10 per week for selling newspaper subscriptions.  He is also paid $3.50 for each new customer (x) that signs up for the subscription.  Which equation represents the amount (y) Daniel earns  per week?

• y = 3.5x

• y= 10 + x

• y = 10 + 35x

• y = 10 + 3.5x

Last Friday Trevon had $29. Over the weekend he received some money for cleaning the attic. He now has $41. How much money did he receive?

• 29 - n = 41

• 29 - n = 40

• 29 + n = 41

• 29 + n = 40

What is the first step to solve this equation:
-3x + 11 = 44

• Add 3 to both sides

• Subtract 11 from both sides

• Add 11 to both sides

• Divide 3 on both sides.

x - 62 = 123
How should you show your work to isolate the variable and solve the equation?

• Add 62 to each side. 

• Subtract 62 from each side.

• Multiply each side by 62.

• Add 123 to each side.

What is the first step to solve this equation:
11 - 3x = 44

• Add 3 to both sides

• Subtract 11 from both sides

• Add 11 to both sides

• Divide 3 on both sides.

Look at the work. What was done incorrectly?

• Don't divide by 2 first

• Don't add 7 to both sides

• It's correct!

• They should have subtracted 7

Look at the work. What SHOULD have been the first step?

• It's correct!

• Subtract 1 on both sides

• Add 5 on both sides

• Divide by 3 on both sides
