Real-Life Scenarios: Solve One-Step Equations

Sarah has 12 apples. She gives some to her friend and now has 7 apples left. How many apples did she give away? (Create and solve the equation: 12 - x = 7)

• 4

• 3

• 5

• 6

A book costs $15. If you have $20, how much money will you have left after buying the book? (Create and solve the equation: 20 - 15 = x)

• 5

• 25

• 0

• 10

Tom has 5 more marbles than Jerry. If Jerry has x marbles, how many marbles does Tom have? (Create the equation: T = x + 5)

• T = x - 5

• T = x + 5

• T = x + 10

• T = 5x

A box contains 24 chocolates. If you eat x chocolates, how many are left? (Create and solve the equation: 24 - x = y)

• y = 24 + x

• y = 24 * x

• y = 24 - x

• y = 24 / x

Lily is 3 years older than her brother. If her brother is y years old, how old is Lily? (Create the equation: L = y + 3)

• L = y - 3

• L = y + 3

• L = y + 5

• L = y - 1

A farmer has 50 apples. He sells x apples at the market. How many apples does he have left? (Create and solve the equation: 50 - x = y)

• x - 50

• 50 * x

• 50 - x

• 50 + x

There are 30 students in a class. If 10 students are absent, how many students are present? (Create and solve the equation: 30 - 10 = x)

• 10

• 25

• 15

• 20

A toy costs $25. If you have $x, how much more do you need to buy the toy? (Create and solve the equation: 25 - x = y)

• 25 - x

• 25 / x

• 25 + x

• x - 25

Emma has 18 stickers. She gives away x stickers to her friends. How many stickers does she have left? (Create and solve the equation: 18 - x = y)

• y = 18 - x

• y = 18 / x

• y = 18 * x

• y = 18 + x

A pizza is cut into 8 slices. If you eat x slices, how many slices are left? (Create and solve the equation: 8 - x = y)

• x slices are left.

• 8 - 2x slices are left.

• 8 - x slices are left.

• 8 + x slices are left.
