if you multiply the 1st equation by two, you get the 2nd equation
... the two equations are basically the same
what does that mean for solutions?
anything that works for the 1st, will also work for the 2nd
What solution(s) does the system of equations have?
-2x + 5y = 10
-4x + 10y = 20
A: There are infinitely many solutions.
B: The only solution is (5,4)
C: The only solution is (10,6)
D: There are no solutions.
