Solve system of equations using any method 2x-6y=8 and 2x-6y=3

Answer 1

The answer is no solution. If you use elimination, by subtracting the second equation from the first, you come out with 0=5, which is a false statement. Therefore, there is no solution.

Answer 2

Let z be any number (like x would be)

if we set z equal to 2x-6y, then we get z = 2x-6y

The system

2x-6y = 8
2x-6 = 3

turns into this new system

z = 8
z = 3

but z is a single number. It can't be both 8 and 3 at the same time. So there are no solutions
