That number quintillion.
Then the number is 20
(a number) + 11 = 11 more than a number
18
hashahahahaha
10
let n=the number n+18
18/8 = 2 and 1/4 in its simplest form
As long as there is no more than a four year age difference.
5x + 18 = 2x - 6 x = -8
factorise it and get your answer- 30=2*3*5 18=2*3*3 same number of factors
4x+x+18 = 14
It's seven
