x + y = 200

\frac{x}{12} + \frac{y}{10} = 18

To solve:
1. Solve for $ y $ from the first equation and substitute in the second:

y = 200 - x

\frac{x}{12} + \frac{200 - x}{10} = 18

2. Clear the denominators by multiplying through by 60:

5x + 6(200 - x) = 1080

5x + 1200 - 6x = 1080

-x + 1200 = 1080

3. Solve for $ x $:

-x = 1080 - 1200

-x = -120

x = 120

4. Find $ y $:

y = 200 - x

y = 200 - 120

y = 80

Hence, the numbers are:

x = 120, \quad y = 80
