The second of three numbers is 5 less than then 4 times the first. The third number is 9 less than twice the first. If 4 times the third is decreased by the first, the result is 6. Find the numbers.

Answer 1

Y=4X-5

Z=2X-9

4Z-X=6

X=4Z-6

X=(9+Z)/2

4Z-6 = (9+Z)/2

8Z-12 = 9+Z

7Z=21

Z = 3

X=4Z-6=12-6 = 6

Y=4X-5 = 4(6)-5 =19

First number is 6

Second is 19

Third is 3
