Question

Make D the subject of formula
A=cd-b

Answer 1

Answer:

$\frac{A+b}{c}=d$

Step-by-step explanation:

We basically have to isolate D by itself, so that involves some addition and division to do so.

Our current equation is:  

$A = cd-b$

So first we move $b$ to the other side via addition.

$A +b=cd-b+b$

$A+b=cd$

Then we move $c$ to the other side by dividing both sides by it in order to cancel it on the right side.

$\frac{A+b}{c}=\frac{cd}{c}$

$\frac{A+b}{c}=d$
