Hey! Okay so we first can take out "y" and put in 27 since the question is stating that y=27. Now we are going to Add 27 to both of the sides to make the problem look like this: 3x-27+27=18+27 Got it? Now we have step 2. Divide 3 by BOTH sides. [tex] \frac{3x}{3} = \frac{45}{3} [/tex] And you get 15, Therefore you have x=15 •❋Korey❋•
