Set up equations to show the relationship between the numbers. Let's call the numbers a and b. We know that a+b=32, and we know that a = b + 12. Now we have two equations in two unknowns, and we can solve them by substituting b+12 wherever we see a in the first equation. That will give us the value of b. Then find a from the value of b and the second equation.
