Question

(y-z)/3 = (y-x)/2 = 5z - 4x,y + z = 2x + 1 how to solve

Answer 1

Answer:

y-z/3=y-z/2

2y-2z=3y-3z

3y-2y=3z-2z

y=z

second step

y+z=2x+1

y+y=2x+1

2y=2x+1

2y-2x=1....2(2)

third step

y-x=10z-8x

9y=7x.

then

9y-7x=0

equ..2

18y-18x=18

18y-14x=0

0-4x=18

x= -9/2

now .

2y=2(-9/2)+1

2y=-8

y= -4

then

z= -4
