Modeling One Step Equations

r + 20 = 27

• r = 7

• r = 47

• r = 13

• r = 20

x - (-2) = 7

• -9

• -5

• 5

• 9

What would be the best first step to solving the equation in one step?

• multiply both sides by ³/₂ 

• divide both sides by 3

• multiply both sides by 3

• subtract ²/₃  from both sides

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

What equation is modeled here?

• x - 6 = 13

• x + 6 = 12

• x + 6 = 13

• x6 = 13

m+13=21

• m=34

• m=8

• m=273

• m=6

Solve for y:
y - 7 = 10

• 17

• -3

• 3

• -17

What equation matches this situation?
Robyn had some video games then bought 4 more.  Now she has a total of 10 games.

• v - 4 = 10

• v + 4 = 10

• 10 - 4 = v

• Answer not Given

k+8=15

• k=23

• k=10

• k=7

• k=11

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
