2xy3 6x3y9 How do I solve this systemSolutiongiven equations

2x-y=-3 6x-3y=9 How do I solve this system?

Solution

given equations are

6x-3y=9------------>(1)

2x-y=-3

multiply second equation by 3 on both sides

3(2x-y=-3)

3*2x -3*y =3*(-3)

6x -3y =-9------------>(2)

from (1),(2) we get 9 =-9 which is not true

so there is no solution to given system of equations
