Question

Solue;
x + y +z=6.
2x+3y + 4z=20.
3x +2y + 5z =22.​

Answer 1

Answer:

x=-3.5,y=11,z=-1.5

Step-by-step explanation:

1. (2x+3y+4z=20)×3
2. (3x+2y+5z=22)×2
3. step1 -step2, we get y+2z=8, eqn 3.
4. now (x+y+z=6)×2.
5. now eqn (2x+3y+4z=20) - step4. we get 5y+22z=22, eqn 6.
6. eqn6 - eqn3, we get 6y=66, therefore y =11.
7. from eqn 3, we get 11+2z=8, therefore z= -1. 5.
8. from the eqn x+y+z=6, we get x+11-1.5=6, therefore x= -3.5
