Question

TIME TO RUN UR BRAIN

When we find the solution of
4x + 8y = 20. & 5x + 10y = 20.
by GRAPHICAL METHOD we find that they have INFINITELY MANY SOLUTION because they are parallel lines BUT when we find their solution using SUBSTITUTION METHOD OR ELIMINATION METHOD OR CROSS MULTIPLICATION METHOD we find
x = 0. &. y = 0
But this is a contradiction for the GRAPHICAL METHOD. Solve this contradiction.

I'll surely MARK U BRAINLIEST if you solve this.

Answer 1

Answer:

hi

given

4x + 8y = 20. & 5x + 10y = 20.

x+2y=5&x+2y=4

and this equation have no solution because

in the respective equation a1/a2=b1/b2≠c1/c2

the answer of both the equation have no solution
