Question

88.1 - 2.3f = 72.46 i know how to do it but at the same time i dont lol

Answer 1

Answer:

$f=6.8$  

Step-by-step explanation:

Given equation:

$88.1-2.3f=72.46$

To solve for the unknown variable $f$.

Solution:

In order to solve for $f$, we will isolate $f$ alone on one side by carrying out math operations to both sides.

We have:

$88.1-2.3f=72.46$

Subtracting both sides by 88.1

$88.1-88.1-2.3f=72.46-88.1$

$-2.3f=-15.64$

Dividing both sides by -2.3

$\frac{-2.3f}{-2.3}=\frac{-15.64}{-2.3}$

∴ $f=6.8$    (Answer)
