Question

to verify graphically that the pair of linear equations a1x+ b1y+c1=0, a2x+b2y+c2=0 where a1/a2 ≠ b1/b2 is consistent and has unique solution. consider the pair of linear equations 2x-y-5=0, x+y-7=0​

Answer 1

Step-by-step explanation:

a1x+ b1y+c1=0, a2x+b2y+c2=0 where a1/a2 ≠ b1/b2 is consistent and has unique solution.

Now, a1=2, b1=(-1), c1=(-5)

a2=1, b2=1, c2=(-7)

So, 2/1 ≠ (-1)

Therefore, the system of linear equations is consistent and has a unique solution
