What are you supposed to 'do' with it ?
There's a very simple reason why no 'solution' is possible:
In order to find a unique solution, you need as many equations
as variables. This is one equation in two variables, so it has

Noah pays $25.20 for non perishable food items to give to the local homeless shelter the price includes a 5% sales of tax. what is the price before tax of the food items?
Answer:
$24
Step-by-step explanation:
From the information you have that the price of items is $25.20 and it includes a 5% tax. From this, you can write the following:
x+0.05x=25.20
Then, you can isolate x to find the price before tax:
1.05x=25.20
x=25.20/1.05
x= 24
According to this, the price before tax of the food items is $24.
