Question

of " is equal to 2 and y equal to 3 is a solution of the pair of linear equations 2x - 3y+a equal to zero ans 2x + 3y - b + 2 equal to zero then which of the following is true

Answer 1

For the given pair of equations 2x−3y=1 and 3x−2y=4;

a2a1=32

c2b1=−2−3=23

c2c1=−4−1=41

k

As the given pair of linear equation satisfies -

a2a1=b2b1

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