**JJ**, Friday, February 22, 2013 at 12:53pmx = 1st number and y = second number

2x + y = 24

2x - y = 12

Can you finish from here? Add the two equations to eliminate y and solve for x.

Then find y.

Be sure to check both x and y in both equations to be sure you are correct.

**Damon**, Friday, February 22, 2013 at 1:00pm2 x + y = 24

y - 2x = 12

4 x = 12

x = 3

y = 24 - 6 = 18

check

6 + 18 = 24 yes

18 - 6 = 12 yes

note you could have written

2 x + y = 24

2 x - y = 12

2 y = 12

y = 6

2x + 6 = 24

x = 9
