Question 523638
the sum of three numbers is 237. the second number is 9 less than two times the first number. the third number is 6 more than three times the first number. what are the three numbers?
------
Equations:
x + y + z = 237
y = 2x-9
z = 3x+6
---------------
Substitute for "y" and for "x"; then solve for "x":
x + (2x-9) + (3x+6) = 237
---
6x - 3 = 237
6x = 240
x = 40
-----
y = 2x-9 = 80-9 = 71
-----
z = 3x+6 = 126
