Question

If the smaller of two numbers is one-half of the larger number and the sum of the two numbers is 63, find the numbers.

Answer 1

21 and 42

Explanation:

Lets say x and y are our numbers. x is the smaller number, y is the larger.

We can construct the equations:

x = 0.5y

x + y = 63

Substitute 0.5y for x in the second equation.

0.5y + y = 63

1.5y = 63

y = 42.

Plug y into the first equation.

x = 0.5 * 42

x = 21.

Your numbers are 21 and 42.
