The sum of two positive integers is 108. One integer is three times as great as the other. Find the integers
.
Let x = smaller integer
and y = larger integer
.
x+y = 108 (equation 1)
y = 3x (equation 2)
.
substitute the value of y from equation 2 into equation 1 and solve for x:
x+y = 108
x+3x = 108
4x = 108
x = 27
.
substitute the above into equation 2 and solve for y:
y = 3x
y = 3(27)
y = 81
.
The two integers are 27 and 81
