Answer:
Infinite solutions
Step-by-step explanation:
2x – y = 6
-3y = -6x + 18
Before substituting, let us simplify the 2nd equation.
-3y = -6x + 18
-y = -2x + 6
we now have
2x – y = 6
-y = -2x + 6
so... we have equivalent equations
Infinite solutions
Substitute y = 2x - 6
2x - (2x - 6) = 6
2x - 2x + 6 = 6
6 = 6
Infinite solutions
