Nothing adds up to 13 and multiplies to 24, but if there are decimals it could work.

Hi Guest!

 

x + y = 13

y = x - 13

xy = 24

 

x(x-13) = 24

x^2-13x+24 = 0 

 

So now we have to use the quadratic equation

x = 13/2 + sqrt(73)/2 

y = 13/2 - sqrt(73)/2 

 

I hope this helped. 

So those are our 2 answers. :)))

nice answer, cat! i was wondering though, what if the question meant more than two numbers? 

for example, 2*3*4 multiplies to 24, but they don't add up to 13. would there maybe be more than just a pair of numbers that could work?
