Model and Solve with One Variable Equations

What would be the best first step to solving the equation?
-3=x+5

• add 3 to both sides

• subtract 5 from both sides

• add 5 to both sides

• subtract -5 from both sides

8 = k/5

• 3

• 13

• 40

• 1.6

-22 + x = -42

• 64

• -64

• 20

• -20

12 = x - (-18)

• 6

• -6

• 30

• -30

Solve the equation:
-5x = 25

• x = 20

• x = -20

• x = -5

• x = 5

Write an equation for the model above.

• x + 3 = -9

• x - 3 = 9

• 3x + 1 = 9

• 3x - 1 = 9

2 + n =16

• 18

• -18

• 14

• -14

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

Which choice models this situation?
Taylor has read 125 pages in a book. The book has a total of 262 pages. How many pages does she have left to read to finish the book?

• p - 125 = 262

• p + 125 = 262

• 125p = 262

• p/125 = 262

Which choice models this situation? Last week, Tina worked 35 hours in 5 days. She worked the same number of hours each day. How many hours did she work each day?

• h - 5 = 35

• h + 5 = 35

• 5h = 35

• h/5 = 35
