Question

Applying factorization method , Solution of the equations     x + 3y + 3z = 16,   x + 4y + 3z = 18  ,  x + 3y + 4z = 19  is

Select one:

a.

x=1/8,y=−9/8,z=−7/8x=1/8,y=−9/8,z=−7/8

b.

x=1,y=2,z=3x=1,y=2,z=3

c.

x=1,y=4,z=−2x=1,y=4,z=−2

d.

x=−1,y=2,z=−3​

Answer 1

Answer:

take x as 14

take y as 29

x × 14 + y × 29

x+ y = 43

x+y = z

z= -2

43- 2
