Y+Z-4X+200=0 (1)
X+Z-7/2Y+200=0 (2)
X+Y-7/8Z+200=0 (3)
(1)-(2):9/2Y-5X=0 (4)
(1)-(3):15/8Z=5X=0
Let y and Z denote formula (1) with X
10/9X+8/3X-4X+200=0
X=900
Y=9/10X=1000
Z=8/3X=2400

Please help us to solve this system of linear equations X: Y: z = 4:5:6 2x + 3y-4z = - 3

Let x = 4A, y = 5a, z = 6A
Then 2 × 4A + 3 × 5a-4 × 6A = - 3
A = 3
So x = 12, y = 15, z = 18
