The sum of two numbers is 38. The greater number is 8 more than the other number. Solve this system using either graphing or substitution. What is the larger number only?

Respuesta :

your two numbers can be called n and n + 8, and together they add up to 38

So n + n + 8 = 38

which means n + n = 30

and since the n's are the same, you just cut the 30 in 2 equal pieces. 15 and 15.

So n = 15, n + 8 = 23

15 + 23 = 38 :-)

Hope this helps!
