Question 1020790: The sum of three numbers is 90.The first number is 6 less than the second. The third number is 4 times the second. What are the numbers Answer by Cromlix(4381) (Show Source):
You can put this solution on YOUR website! Hi there,
Make the second number = 'x'
First number = x - 6
Third number = 4x
(x - 6) + x + 4x = 90
x - 6 + x + 4x = 90
Collect like terms:
x + x + 4x = 90 + 6
6x = 96
x = 16
First number = 10
Second number = 16
Third number = 64
Hope this helps :-)
