Question

Find the value of ‘m’ for which the system of equations mx + 2y = 5, 3x + y = 1 has unique solution?

Answer 1

Answer:

9

Step-by-step explanation:

As both equations has same solution, I will assume a point (1,-2) which satisfies 3x+y=1

substituting same point in the equation mx+2y=5

m*1+2*(-2)=5

m-4=5

m=9
