Answer:

12

Step-by-step explanation:

3x + 6 = 42

subtract 6 on both sides

3x = 36

divide 3 on both sides

x = 36 ÷ 3 = 12

Hey!

The first thing we do is subtract 6 From both sides (or, 6 from 6 and 6 from 42)

Now you equation is 3x=36

Now you didvide 3 from both sides, to isolate x.

3/3= 1 (But because X is there, we just say X)

Now, 3/36.

3/36 is 12

So, your answer is

X=12
