Two Step Equations

WRITE AN EQUATION: Jasmine paid $25 for two binders and one pack of pens. The pack of pens costs $5. What is an equation you can use to find the price of each binder?

• 25 = 2x + 5

• 25 = 2 + 5x

Aliyah had $24 to spend on seven pencils. After buying them she had $10. How much did each pencil cost?

• 24 - 10 = 7x

• 7x - 24 = 10

331 students went on a field trip. Six buses were filled and 7 students traveled in cars. How many students were in each bus?

• 7x + 6 = 331

• 13x = 331

• 6x + 7 = 331

• 331 - 7 = 6x

Which equation would describe "two times a number plus five equals 15"?

• x + 5 = 15

• 2x + 5=15

• x + 2(5) = 15

• 2(x + 5) = 15

Scott works on cars. He charges $35 for each car plus $7 per hour.
The correct equation was 7x + 35 = 63.
So, how many hours did he work on Kylie's car if her bill was $63?

• x = 4

• x = 5

• x = 3

• x = 4.5

Jim paid a gym membership fee of $50, plus $20 per month.  Jim has paid a total of $290 to the gym.  How many months has Jim been a member of the gym?

• 50 + 20m = 290

• 20 + 50m = 290

• 50 + 20 = m

• 50m - 20 = 290

The steps in solving 5b - 6 = 24 are: 

• Add 6 to both sides and divide both sides by 5

• Add 6 to both sides and multiply both sides by 5

• Subtract 6 from both sides then multiply both sides by 5

• Subtract 6 from both sides then divide both sides by 5

In this soccer season, Emma has scored 1 more than twice the number of Nick's goals.  If Emma has scored 15 goals, which equation can be used to find x, the number of Nick's goals?

• x - 15 = 1

• x + 1 = 15

• 2x + 1 = 15

• x + 1 = x + 15

What is the solution to this equation?

• 6.032

• 3.512

• 12.6

• 2.52

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
