10a+5.50c=31
What are the steps to solve this

Step-by-step explanation:

There are 2 variables a and c, and there is only 1 equation. Hence we cannot find both variables.

However if we restrict a and c to be positive integers, we will have:

10a + 5.5c = 31

=> 20a + 11c = 62

Since 62 ≡ 2(mod 20) and 11c <= 62,

we have c = 2.

=> 20a + 11(2) = 62, 20a = 40, a = 2.

Therefore a = 2 and c = 2.

Hopefully this explanation helped!
