Question

What is a + ar = 3 solving for r?

Answer 1

First subtract a

you are left with
ar=3-a
then divide both sides by a
$\frac{ar}{a} = \frac{3 - a}{a}$
the A's cancel out and you are left with
$r = \frac{3 - a}{a}$

Answer 2

Hello there!

Solve for r.

$a + ar = 3$

Explanation:

↓↓↓↓↓↓↓↓↓↓↓↓

First you had to add -a from both sides of the equation.

$ar+a+-a=3+-a$

$ar=-a+3$

Then you divide by a from both sides of the equation.

$\frac{ar}{a}=\frac{-a+3}{a}$

$r=\frac{-a+3}{a}$

Answer⇒⇒⇒⇒r=-a+3/a

Hope this helps!
