88.1 - 2.3f = 72.46<br><br> i know how to do it but at the same time i dont lol
d1i1m1o1n [39]

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)
