Estelle is helping at a community food drive by boxing up cans of soup. There are two sizes of boxes, large and small. Estelle f
podryga [215]

Answer:

The small box contains 21 cans

<em></em>

Step-by-step explanation:

Represent the small box with S and the large with L.

For Estelle:

3L + 5S = 170

For the boy:

4L + 4S = 184

Required

Determine the cans in the small box

3L + 5S = 170 --- (1)

4L + 4S = 184 --- (2)

Divide (2) through by 4

L + S = 46

Make L the subject

L = 46 -S

Substitute 46 - S for L in (1)

3L + 5S = 170

3(46 - S) + 5S = 170

Open bracket

128 - 3S + 5S = 170

128 + 2S = 170

Collect Like Terms

2S = 170-128

2S = 42

Divide both sides by 2

S = 21

<em>Hence, the small box contains 21 cans</em>
