# The value of k fo

Given:

Equation 1: x + 2y = 5

Equation 2: 3x + ky = – 15

Both the equations are in the form of :

a1x + b1y = c1 & a2x + b2y = c2 where

a1 & a2 are the coefficients of x

b1 & b2 are the coefficients of y

c1 & c2 are the constants

For the system of linear equations to have no solutions we must have ………(i)

According to the problem:

a1 = 1

a2 = 3

b1 = 2

b2 = k

c1 = 5

c2 = – 15

Putting the above values in equation (i) and solving we get:

### Thevalue of k for which the system of equations has no solution is k = 6
