Solving One, Two, and Three Step Equations

What are the steps to solving 5y - 6 = 24?

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

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

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

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

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

• n = -3/4

• n = 3/4

• n = -48

• n = 48

• h = 150

• h = 20

• h = 6

• h = 4/5

Solve the following algebraic equation for e.

3.2e + 2.6 = -23

• e = 6.375

• e = 8

• e = -8

• e = -6.375

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

Scott works on cars. He charges $35 for each car plus $7 per hour. Write an equation that represents this scenario if Kylie's car bill was $63.

• 7x + 35 = 63

• 7x = 63

• 7x - 35 = 63

• 35x + 7 = 63
