Question

make f the subject of the formula d=3(1-f)/f-4

URGENT HELP PLEASE!!!!!!

Answer 1

Answer: $f=\frac{3+4d}{d+3}$ will be the formula when f is the subject of the formula.

Given: We are given a formula $d=\frac{3(1-f)}{f-4}$

To Find: We have to make f as the subject of the formula.

Step-by-Step Explanation: To solve this question we will perform simple algebraic manipulations on the given formula to get the final formula in which f is the subject of the formula.

Step 1: $d=\frac{3(1-f)}{f-4}$

Cross-multiplying:

$df-4d=3-3f$

Step 2: Taking all the terms containing f towards the left side of the equation and the rest others towards the right side of the equation.

$df+3f=3+4d$

Step 3: Taking f common in the left side of the equation: $f(d+3)=3+4d$

Dividing both sides by (d+3): $f=\frac{3+4d}{d+3}$
