Question

Solve D = ABC for A

A = ???

Answer 1

What are you getting stuck on?

Answer 2

\[D = ABC\]divide both sides by B
\[\frac DB = \frac{ABC}B\]
\[\frac DB=AC\]now divide both sides by C
\[\frac D{BC}=\frac{AC}C\]
and simplify

Answer 3

The whole thing....

Answer 4

Well, A is being multiplied by BC, so do the opposite of multiplication to get it to the other side with D

Answer 5

D=ABC
A=D/BC

Answer 6

not having numbers threw me. I never thought of eliminating each variable leaving you with A = D/BC

Answer 7

Can you solve this

4=2x?

Answer 8

whatever you are solving for, treat that as the only variable, and everything else as a constant if that helps, and move everything to the other side like you would with normal numbers

Answer 9

If ax=b then x=b/a
