One Step Equations with Mr. J

in 3a =12,
I would....

• add 3 to both sides

• subtract 3 from both sides

• divide both sides by 3

• divide just the right by 3

a ÷ 5 = 30

• a = 6

• a = 30

• can't be solved

• a = 150

Solve the equation
3x = 27. 

• x = 24

• x = 81

• x = 9

Cheryl gets paid $8 per hour for her job at the record store.  She made a total of $96 last week.  Which equation models this situation?

• 96h = 8

• h/96 = 8

• 8h = 96

• h/8 = 96

Ted bought a dolphin poster for $12.  He now has $5.  Which choice models this situation?

• m - 12 = 5

• m - 5 = 12

• m + 5 = 12

• m + 12 = 5

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

• Add 3 to both sides

• Subtract 3 from both sides

• Multiply 3 on 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.

Which choice models this situation? Marcus needs to sell 25 tickets to a fundraiser by Friday. So far, he has sold 9 tickets. How many tickets does he still need to sell?

• t - 9 = 25

• t + 9 = 25

• 9t = 25

• t/9 = 25

Sally bought three candy bars for a total of $18.00. How much did each candy bar cost? Write an equation to solve this problem. Use c as your variable.

• 18c=6

• c + 6= 18

• c +18 = 6

• 3c=18

After dropping 5ºF, the temperature was 37ºF. Which choice models this situation?

• d - 37 = 5

• d + 5 = 37

• d - 5 = 37
