Answer 2

Step-by-step explanation:

discuss the nature of solution

x+2y-2=6 -----------------eq(1)

-3x-2y+5z=-12 -------------eq(2)

x-22=3 --------------------eq(3)

in eq,(3)

x = 3+22

x =25

in eq(1)

x+2y-2=6

x+2y=8 (put the value of x)

25+2y=8

2y=8-25

y= -17/2

in eq(3)

-3x-2y+5z= -12

5z= -12+3x+2y (put the value of x&y)

5z= -12+3(25)+2(-17/2)

5z = -12+75-17

5z =75-29

5z =46

z=46/5

x=25 , y= -17/2 , z=46/5
