Write Equations in One Variable

Mario picked plums off a tree in the yard.  He gave

18 plums to a neighbor and had 34 left.  Which

equation, when solved, will tell how many plums

Mario picked?

 18 - p = 34

 p ÷ 18 = 34

 p - 18 = 34

 p - 18 = 34

A toy company is going to use 6 boxes to ship some

toys across the country.  The company needs to ship

24 toys.  Which equation, when solved, will tell how

many toys the company should put in each box?

 6 x t = 24

 t x 24 = 6

 t - 6 = 24

 t ÷ 6 = 24

Jenna put some staples into an empty stapler.  After

Jenna used 12 staples to make paper chains, there

were 69 staples left in the stapler.  Which equation,

when solved, will tell how many staples Jenna put

into the stapler?

 s + 12 = 69

 s - 12 = 69

 12 - 69 = s

 s ÷ 12 = 69

Shane and Camille had 82 books.  They divided them

into equal piles.  Each pile had 2 books.  Which

equation, when solved, will show how many piles

of books there were.

 82 ÷ p = 2

 82 x p = 2

 41 x 2 = p

 82 - p = 2

LSU needed to transport 28 fans to its football

game from the stadium parking lot.  The university

rented a bunch of vans and put 4 fans in each van.

Which equation, when solved, will tell the number

of vans that the university rented?

 28 ÷ v = 4

 28 - v = 4

 v ÷ 28 = 4

 4 ÷ 28 = v

Elise has 48 blue blocks.  When she mixes them with

her red blocks, there are 66 block in all.  Which

equation, when solved, will show how many red blocks

Elise has?

  r + 66 = 48

 48 + 66 = r

 48 + r = 18

 48 + r = 66

Meredith took some almonds from a bowl.  She ate

17 of them and had 16 almonds left.  Which equation,

when solved, will tell how many almonds Meredith

took from the bowl?

 a x 17 = 6

 a - 17 = 16

 16 - a = 17

 a - 17 = 17 - 16

There are 65 boys in the school choir.  The choir has

91 members in all.  Which equation, when solved,

will show how many girls are in the school choir?

 g x 65 = 91

 65 - g = 91

 65 + g = 91

 g - 65 = 91

Desmond runs 6 miles every day.  Which equation,

when solved, will tell how many days it will take

Desmond to run 54 miles?

 6 x d = 54

 d x 54 = 6

 d + 54 = 6

 d - 54 = 6
