Answer:
18
Explanation:
Let's use x and y
x + y = 42
1/3x = 1/6y + 5
Multiply by 3 on both sides
x = 1/2y + 15
SUBSTITUTE X
1/2y + 15 + y = 42
Combine the two ys
1 1/2y + 15 = 42
minus 15 on both sides
1 1/2y = 27
y = 18
Now, find x by substituting y
x + y = 42
x + 18 = 42
x = 24
X is the greater number, y is the smaller number.
The smaller number is 18
