Question

Solve for b. C=4a+4b

Answer 1

In order to solve for "b", you have to find an expression b = ...

To do it, first, subtract 4a from both sides of the equation.

$\begin{gathered} c-4a=4a+4b-4b \\ c-4a=4b \end{gathered}$

Now, divide both sides by 4:

$\begin{gathered} \frac{c-4a}{4}=\frac{4b}{4} \\ \frac{c-4a}{4}=b \end{gathered}$

Which is the same as:

$b=\frac{c-4a}{4}$

Answer:

$b=\frac{c-4a}{4}$
