3f - 2 = 4f + 5
You are looking for an unknown number, f. In the end, you want to know that f equals a specific number; the number on one side of the equation and f on the other. So first you want to get it in that format:
-2 = 5 + 4f - 3f
-2 - 5 = 4f - 3f
Now solve:
-7 = f
You can see that f equals -7. This is what you're looking for.

What is 3f plus f plus 4f equal?
When you have 3f plus f plus 4f, you are adding together like terms. In this case, the variable "f" is the same, so you can add the coefficients together. 3f + f is 4f, and when you add 4f to that, you get 8f. Therefore, 3f + f + 4f equals 8f.
7f - 2e - 3f plus 4e?
It can be simplified to: 4f+2e
What is 4f plus 2 plus 3d-1-3f?
It is an expression and can be simplified to: 3d+f+1
What are odd and even harmonics?
A harmonic of a wave is a component frequency of the signal that is an integer multiple of the fundamental frequency. If the fundamental frequency is f, the harmonics have frequencies f, 2f, 3f, 4f, etc. Even harmonics are 2f, 4f, 6f, ... Odd harmonics are f, 3f, 5f, ... And remember: Even harmonics 2f, 4f, 6f,... are odd overtones. Odd harmonics f, 3f, 5f,... are even overtones. Scroll down to related links and look at "Calculations of harmonics from fundamental frequency".
