Question 711370
The best way to answer is through simple algebra.  A bad way to answer is trial & error.  


First translate into variables and expressions.  two numbers, x, and y.  Sum is 56, difference is 8.


x+y=56, and y-x=8,  or x-y=8 depending on which you want as greater.


from y-x=8, add x to both sides getting y=8+x.
Substitute into the sum equation and solve for x.
x+(8+x)=56
x+8+x=6=56
2x=56-8
2x=48, x=6, so what is y?
