Getting A

1x+2y+3z=(3/2)(x+y+z)
2x+4y+6z=3(x+y+z)
2x+4y+6z=3x+3y+3z

Solving for x:
y/3+z=x/3 --> x=y+3z

Same solution as above, got A

(.001x+.002y+.003z)/(x+y+z) = 1.5

simplifying the equation,

by cross multiplying, and then subtracting like terms, multiplying by 1000 on both sides,

we get 5y+15z=5x

that is y+3z = x
