S=4F-5
T=2F-9
4T-F=6
does that help?
THe second of three numbers is 5 less than 4 times the first. The third is 9 less than twice the first. If 4 times the third os decreased by the first, the result is 6. find the three numbers.

1st number = x,
2nd number = 4x - 5,
3rd numbe = 2x - 9,
4(2x - 9) - x 6,
8x - 36 - x = 6,
7x 42,
x = 6 = 1st number.
(4x - 5) = 4*6 - 5 = 19 = 2nd number.
(2x - 9) = 2*6 - 9 = 3 = 3rd number.
.
2nd number = 4x - 5,
3rd numbe = 2x - 9,
4(2x - 9) - x 6,
8x - 36 - x = 6,
7x 42,
x = 6 = 1st number.
(4x - 5) = 4*6 - 5 = 19 = 2nd number.
(2x - 9) = 2*6 - 9 = 3 = 3rd number.

CORRECTION:
4(2X - 9) - X = 6.
4(2X - 9) - X = 6.
