slava [35]

I'm not sure how many equations you are asking for, but hopefully, you can use what I wrote here to solve your actual question. Here is my go:

Given:

Evan paid his mom back 9.60 which is 20% of the total he owns.

To find:

How much did he owe her to begin with.

Solution:

Let x be the amount Evan owns.

According to the question,

20% of x = 9.60

$\dfrac{20}{100}x=9.60$

$\dfrac{1}{5}x=9.60$

Multiply both sides by 5.

$x=48$

Therefore, Evan owns 48 from his mom.
