Answer:
Option D is right,.
Step-by-step explanation:
-a+4b+2c=-8 ... i
3a+b-4c=9 ... ii
b=-1 ... iii
Substitute the value of b, in i and ii
-a-4+2c =-8 or -a+2c = -4
and 3a-1-4c = 9 or 3a -4c =8
Now we have two equations in two variables
-a+2c =-4 and 3a-4c =8
a = 2c+4: substitute this in the other equatin.
3(2c+4)-4c =8 Or 2c +12 =8
2c =-4 or c = -2
Substitute in -a+2c =12
-a-2 = -4
a = -2+4 =2
a=2, b=-1 and c =-1 is the solution.

Answer:
m<1=?
m<2=4x-20..........(1)
m<4=3x-11.............(2)
Step-by-step explanation:
we have
- m<2=m<4(corresponding angle of parrelelogram are equal)
- 4x-20=3x-11
- 4x-3x=20-11
- x=9
again.we have
<1+<2=180(co-interior angle)
<1=180-<2=180-(4×9-20)=180-16=164
