Question

3 packs of soda cost $10 less than 5 packs of soda. Write an equations that models this.

Answer 1

Let, the cost of 1 soda = x

A.T.Q,

3x+10 = 5x

5x-3x = 10

2x = 10

x=5

so, cost of 1 soda pack would be $5

Answer 2

`3x=5x-10`

Explanation:

Let x be the cost of one pack of soda.

Cost of 3 packs=
`3x`

Cost of 5 packs of soda=
`5x`

We have to write an equation that model this.

According to question

`3x=5x-10`

`5x-3x=10`

`2x=10`

`x=(10)/(2)=5`

Hence, the equation is given by

`3x=5x-10`
