Question

What is the solution to the system of equations? 3x - 6y = - 12 x - 2y = - 8 Use the substitution method to justify that the given system of equations has no solution.​

Answer 1

There is no solution to this system.

Explanation:

The left side of the first equation is 3 times the left side of the second one.

If we multiply the whole of the second equation by 3 we get:

3x - 6y = -16.

As the first equation is 3x - 6y = -12 we see that there is no solution to this system. 3x - 6y can't be equal to -12 and -16.
