A) x4=y+29=z312\frac { x } { - 4 } = \frac { y + 2 } { - 9 } = \frac { z - 3 } { 12 }
B) x4=y+29=z312\frac { x } { - 4 } = \frac { y + 2 } { 9 } = \frac { z - 3 } { 12 }
C) x4=y+29=z312\frac { x } { 4 } = \frac { y + 2 } { - 9 } = \frac { z - 3 } { 12 }
D) x4=y+29=z312\frac { x } { 4 } = \frac { y + 2 } { 9 } = \frac { z - 3 } { 12 }
E) x9=y+24=z312\frac { x } { 9 } = \frac { y + 2 } { - 4 } = \frac { z - 3 } { 12 }
