The values of (x,y,z) are (3,-1,-2) , if the given are equations ,
and
.
Step-by-step explanation:
The given is,
.......................................(1)
......................................(2)
.........................................(3)
Step:1
Equation (2) is multiplied by -1 ( Eqn(2) × -1 )
.............................(4)
Subtract the equation (1) and (4)
( - )
......................(5)
Step:2
Equation (2) is multiplied by -2 ( Eqn(2) × -2)
........................(6)
Subtract equation (6) and (3),
( - )
z = -2
From the equation (5),
x = -1
From equation (1),
Substitute x and z values,
y = 1
Step:3
Check for solution,
Substitute x,y and z values,
-5 = -5
Result:
The values of (x,y,z) are (3,-1,-2) , if the given are equations ,
and
.
