Question

How do you do the problem uka=a+b solve for a

Answer 1

When we make a the subject of formula in $uka=a+b$, we have: $a=\frac{b}{uk-1}$

Given the following equation:

• $uka=a+b$

To make a the subject of formula:

In this exercise, you're required to make a variable (a) the subject of the given formula.

Therefore, the variable (a) would be recognize as the most important part of the given formula and as such, it would be made to stand on its own on the left side of the equals to sign (=).

First of all, we would rearrange the equation by collecting like terms.

Moving a to the left side of the equals to sign (=), we have:

$uka - a = b$

Next, we would factorize the value of a:

$a(uk-1)=b$

Lastly, we would divide both sides by uk - 1:

$a=\frac{b}{uk-1}$
