Question

n-2y=0 and 3X+4y-20=0​

Answer 1

Solution:- (A) one solution

For the given pair of equations x−2y=0 and 3x+4y=20;

4y=20;

a1 =. 1

a2. 3

b1 = -2 = -1

c2. 4. 2

c1 = 0 = 0

c2. -20

As the given pair of linear equation satisfies

a1 ¥ b1

a2. c2

The graph will be a pair of lines intersecting at a unique point, which is the solution of the pair of equations.
