Question

How many solutions are there to this system of equations? Explain how you know.

y=3x-2
3x-y=7

Answer 1

The following system of equation has no solution.

Explanation:

since both of them are equal to y, set them equal to each other:

3x+1=3x+7

if you subtract both sides by 3x, you get 1-7. That is a contradiction, so this
