Question

by using quardatric formula show that x-2y=8 and5x-10y=10​

Answer 1

Answer:

The given system of equations is:

x – 2y – 8 = 0

5x – 10y – 10 =

The above equations are of the form

a1 x + b1 y − c1 = 0

a2 x + b2 y − c2 = 0

Here, a1 = 1, b1 = -2, c1 = −8

a2 = 5, b2 = -10, c2 = −10

So according to the question, we get

a1/a2 = 1/5

b1/b2 = −2/−10 = 1/5 and,

c1/c2 = −8/−10 = 4/5

⇒ a1/a2 = b1/b2 ≠ c1/c2

Hence, we can conclude that the given system of equation has no solution.
