Answer:

8.7

Step-by-step explanation:

one way that works the best, since you have your unknown variable ( a ), you will have to move -3.2 over to the side where 5.5 is. after you do that, you have to add together the 3.2 and the 5.5 because whenever you do something like that, you have to do the opposite of that. hope that made sense!

Katyanochek1 [597]
The original number is 72 


(18+x)/6 = 1+14 
1/6x + 3 = 1 + 14 (Distribute)
1/6x + 3 = (1+14) (Combine Like Terms)
1/6x + 3 = 15 
        - 3 = -3          (Subtract 3 From Both Sides)
1/6x = 12 
(1/6x)*6 = 12 * 6  (Multiply Both Sides By 6)
x = 72
