3 packs of soda cost $10 less then 5 packs of soda. Write the equations that modes this

3 packs of soda ... $x - $10

5 packs of soda ... $x

We would like to know what is the value of the x.

3 * x = 5 * (x - 10)

3 * x = 5 * x - 50

50 = 2 * x

x = $25

Result: 5 packs of soda cost $25 and 3 packs of soda cost $25 - $10 = $15.
