Question

Help me.......
c + 11=20;c=9

Answer 1

All you have to do is add 9(or c) to the equation. If c is 9, then you just have to do 9 + 11 which would equal 20.

Answer 2

Explanation:

If you are confused as to how the answer is 9 then all we have to do is solve for c

c + 11 = 20

So in order to solve this you have to subtract 11 from 20 to get c alone on one side so...

c = (20-11)

c = 9
