Select two variables, set up two equations and solve the problem below. The sum of two integers is 45. The larger is 3 less than three times the smaller. Find the two integers.
***
let x=larger integer
let y=smaller integer
..
x+y=45 (sum of two integers is 45)
x=45-y
x=3y-3 (larger is 3 less than three times the smaller)
45-y=3y-3
4y=48
y=12
x=45-y=33
larger integer=33
smaller integer=12
