Answer 1

i think i have to make a table?
x/y
6/18
3/9
1/6

the larger number is y so is the larger number 18?

Answer 2

Basic algebra question:

let the large number be x
let the smaller number be y

x - y = 12
x + 3y = 20
subtract them
4y = 8
y = 2
in x-y=12
x -2=12 ---> x = 14

the larger number is 14, the smaller is 2
