Answer:
The numbers are 21 and 8.
Explanation:
Let x be the larger number and y be the smaller number.
According to question,
x + y = 29
or x = 29 - y ........(i)
Also,
3x + 6y = 111
Replacing x from (i), we get,
3(29-y) + 6y = 111
87 - 3y + 6y = 111
3y = 111 - 87
3y = 24
y = 24/3
y = 8
And,
x = 29 - y
= 29 - 8
= 21
