Question 825519: If from twice the greater of two numbers 17 is substracted, the result is half the other number.
If from half the greater number 1 is substracted, the result is two thirds of the smaller number.What are the numbers?
You can put this solution on YOUR website! ---
x = smaller number
y = larger number
---
x/2 = 2y - 17
y/2 - 1 = (2/3)x
---
put the system of linear equations into standard form
---
(x/2 = 2y - 17)2
(y/2 - 1 = (2/3)x)6
---
x = 4y - 34
3y - 6 = 4x
---
x - 4y = -34
4x - 3y = -6
---
