You can put this solution on YOUR website! if two is added to a number and the sum is tripled, the result is 20 more than the number
let the number bex
2 added to the number = x+2
sum is tripled = 3(x+2)
20 more than the number == x+20
3(x+2)=x+20
3x+6 = x+20
3x-x=20-6
2x=14
x=14/2
x=7 which is the number
