Question

find whether the following pair of linear equation is consistent or inconsistent 2x+2y=8 & 6x-4y=9​

Answer 1

Answer:

inconsistent is tour answer

Answer 2

Answer:

Plot point (0,1) and (1,0) and join to get the equation 2x−2y=2 on a graph 4x−4y=5⇒4x−5=4y

⇒44x−5=y

x045y −450Plot point (0,−45) and (45,0) and join them to get the equation 4x−4y=5 on a graph.

The two lines never intersect, so, the solution is inconsistent.

Step-by-step explanation:

−2y=2   ...(i)

4x−4y=5  ...(ii)

2x−2y=2⇒2x−2=2y

y=x−1

x01y−10
