You can put this solution on YOUR website! larger + smaller = 18
s the smaller number, Larger
....
(2s + 3) + s = 18
3s = 15
s = 5,the smaller number. Larger is 13
and...checking
sum = 18
...
2.
(2s+3) - s = 25
s = 22, the smaller number. Larger is 47
and...checking

Let smaller number be S
Then larger = 18 - S
Therefore, 18 - S = 2S - 3
- S - 2S = - 3 - 18
- 3S = - 21
S, or smaller number = , or
Larger number: 18 - 7, or
Can you do "2" now?
