Respuesta :

first subtract a

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

Hello there!

Solve for r.

[tex]a + ar = 3[/tex]

Explanation:

↓↓↓↓↓↓↓↓↓↓↓↓

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

[tex]ar+a+-a=3+-a[/tex]

[tex]ar=-a+3[/tex]

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

[tex]\frac{ar}{a}=\frac{-a+3}{a}[/tex]

[tex]r=\frac{-a+3}{a}[/tex]

Answer⇒⇒⇒⇒r=-a+3/a

Hope this helps!
