Question

Find the value of m for which the given simultaneous have unique solution. mx+5y=11;14x=15-7y.​

Answer 1

Step-by-step explanation:

For unique solution

They have only one intersection point

14x+7y=15

mx+5y=11

a1/a2not equal to b1/b2

14/m not equal to 7/5

Solving

m must not be equal to 10

So m can have any value except 10.
