Answer:

The two numbers are 494 and 504

Explanation:

Let x = one of the numbers

Let y = the other number

x + y = 998

x - y = 10 or x = y + 10

Substitute y + 10 for x in the first equation and solve for y

x + y = 998

y + 10 + y = 998 Subtract 10 from both sides

y + y = 988 Combine like terms

2y = 988 Divide both sides by 2

y = 494

One of the numbers is 494.

x = y + 10 Substitute 494 for y

x = 494 + 10

x = 504

The other number is 504.

Check:

x + y = 998

504 + 494 = 998

998 = 998 checks

x - y = 10

504 - 494 = 10

10 = 10 checks
