Question

check whether 2x +y - 6=0 and 4x - 2y -
4 =0
Consistent / inconsistent. If consistent
obtain the solution graphically​

Answer 1

Step-by-step explanation:

given,

2x+y-6=0 ->equation1

4x-2y-4=0->equation2

from eq 1

=> a1 = 2,b1 = 1,c = -1 ->equation 3

from eq 2

=> a2 = 4,b2 = -2, c2 = -4 -> equation 4

from eq 3&4

a1/a2≠b1/b2≠c1/c2

therefore given equations are not consistent

Answer 2

Answer:

2x +y - 6=0

if y=0

2x +0- 6=0

2x +6=0

x=6/2

=3

if x=0

2x +y - 6=0

2(0) +y - 6=0

0+y-6=0

y=6

x 3 0

y 0 6

(x,y) (3,0) (0,6)

4x - 2y -4 =0

if x=0

4(0)-2y-4=0

0-2y-4=0

-2y=4

y=4/2

=2

4x - 2y -4 =0

if y=0

4x - 2(0) -4 =0

4x - 0 -4 =0

4x -+4 =0

x=4/4

=0

x 0 0

y 2 0

(x,y) (0,2) (0,0)
