Question

1. The sum of two numbers is 64. One of the numbers is 16 more than 3 times the other. Find the

two numbers.

Answer 1

The two numbers are 52 and 12.

Explanation:

x+y=64

x=16+3y

Now, substitute the second equation into the first one.

16+3y+y=64

16+4y=64

4y=48

y=12

Substitute 12 into one of the equations in order to find x.

x=16+3(12)

x=16+36

x=52
