Question

(3x-4y-2z) from (x+y+z)

Answer 1

$\huge\fcolorbox{lime}{aqua}{Answer}$

3x-4y+2z=0 ---(i) & 4x -2y - z=0 ---(ii)

Multiplying (ii) by 2, 8x - 4y -2z =0 ---(iii)

Adding (i) & (iii), 11x=8y or x/y=8/11 ---(iv)

Subtracting (iii) from (i), 5x=4z or x/z= 4/5 ---(v)

From (iv) & (v), x: y: z = 8 : 11 :10

Answer 2

Answer:

3x-4y+2z=-1

2x+3y+5z=7

x+z=2
