Answer:
x1-2x2-x3= -2
Step-by-step explanation:
Substitute the three points to get three equations:
a1+0a2+ 3a3=d --------------eq i
a1+a2+a3=d----------------eq ii
-2a1-a2+2a3=d---------------eq iii
subtract eq i from eq ii
a2-2a3=0 ----------- eq iv
now add eq iv to eq iii
-2a1=d ------- eq v
put eq v in eq i
a1 + 3a3=-2a1
a3= -a1 ----------- eq vi
put eq vi in eq iv
a2-2(-a1)=0
a2= -2a1 ------ eq vii
put eq v, eq vi and eq vii in the equation of plane
a1x1+ a2x2+a3x3=d
a1x1 -2a1x2-a1x3=-2a1
x1-2x2-x3= -2
