Question

one number exceeds another by 12 . the sum of the number is 32 what are the numbers?

Answer 1

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.

Answer 2

20,12

Answer 3

Bingo!
