three packs of soda cost $10 less than five packs of soda right equation that models this

Answer 1

Hi, Zoie.

Okay, let's call the price of a pack of soda, x.

So 3 packs of soda (3x) costs $10 less than 5 packs of soda (5x).

So, the equation is:

3x = 5x - 10

Now, solve for x:

3x - 3x = 5x - 3x - 10

0 + 10 = 2x - 10 + 10

10 = 2x

10/2 = 2x/2

x = 5

Therefore, a pack of soda costs $5.

Answer 2

Let the cost of a pack of soda be x, then

3x = 5x - 10

x = 5
