Question

can anyone solve this question​

Answer 1

Answer:

x=2

y=-1

z=1

Step-by-step explanation:

solving 1 and 2 equations first

then solving 1 and 3 equations

two equations formed are further solved and

we can get the answer

Answer 2

Answer:

so, x+z=3[i]

then,y=-1

so, 2x=1+3z

or, 2x-3z=1[ii]

now, [i]x3+[ii]x1=

3x+3z=9

2x-3z=1

so, 5x=10

or, x=2

now x+y+z=2

or, 2+(-1)+z=2

or,z=1

.

. . x=2

y=-1

z=1
