Question 87132
let smaller number be x and larger one y


we are told 2 things: 


1. one number is 12 more than the other --> y = 12 + x


2. the larger number is 7 times the smaller number --> y = 7x


so both equations have "y equals" so if y equals both things then surely both those must be the same?


So we get 12 + x = 7x
12 = 6x
so x = 2
and therefore y = 18
