x + 2y = 6
cx - 4y =8
Please show all the stepas, to this equation. thanks
What value of c would give a system with no solution? Math help!!?
multiply 1st equation by -2 to match up y coefficients:
-2x - 4y = -12
cx - 4y = 8
if c = -2 there will be no solution, since
-2x - 4y cannot equal both -12 and 8
