Answer:

A

Step-by-step explanation:

3x+14=20

Here you need to do the inverse operation of +14 to isolate the 3x. The inverse operation would be -14 so you subtract 14 on both sides.

3x+14=20

-14 -14

3x=6

Now you have 3x=6 so you have to do the inverse operation of times 3. The inverse of that is dividing so you divide 3 by 3 and 6 by 3. 3/3 is 1 and 6/3 is 2

(3/3)x=(6/3)

x=2
