A numbmer is divided by 2, then 6 is submtacted from the result.

Question

what operations are needed to return to the original number?
I am going to say:
x/2 -6 the operations needed are
multiplication and addition to get right answer?

Answer 1

R=Result

x/2-6=R Multiply both sides with 2

x-12=2R

x = 2R+12 = 2(R+6)

Answer 2

i don't understand what you did?
X/2 - 6 = R
+ 6 +6

X/2 = R + 6
* 2 = * 2
x = 12
is the answer the operations needed multiplicaton and addition to get right answer?
