Answer:

<h3>x = (y-5)/3</h3>

=========================================

Explanation:

We start with x and multiply it with 3 to get 3x. Then we add on 5 to get 3x+5. This specific order is going to be followed in reverse to undo everything so we can isolate x.

We'll subtract 5 from both sides to undo the "plus 5" operation. Then we'll divide both sides by 3 to undo the "multiply by 3" operation.

---------

This is what the steps look like

y = 3x+5

y-5 = 3x+5-5 ... subtract 5 from both sides

y-5 = 3x

3x = y-5

3x/3 = (y-5)/3 ... divide both sides by 3

x = (y-5)/3
