Find positive integers that satisfy

(x, y, 2) = (1, 2, 3)
Explanation:
The equations that result from reduction
to row-echelon form are ..
x = 0.4 +0.2t
y= 5.6-1.2t
Z =t
Then t must have a value 5nt3 for 0 S n<
1. That is, t=3.
x = 0.4 +0.2(3) = 1
y= 5.6 -1.2(3) = 2
Z =3
The integers that satisfy are (x, y, z) = (1,
The integers that satisfy are (x, y, z) = (1,2, 3).
