Question 121553: can you please help me solve this one.
One number exceeds another by 10. The sum of the numbers is 8. What are the numbers? What I had for the equation was x+x+10=8

this is a problem involving solving a system of equations. The system is as follows:
y = x + 10
x+y = 8
now we just plug in the first equation into the second one and solve for x.
x + x + 10 = 8 --> combine like terms
2x + 10 = 8 --> Subtract 10 from both sides
2x = -2 --> divide both sides by 2
x = -1
now that we have a value for x plug that into the first equation and solve for y.
y = -1 + 10
y = 9
