Question 463131: 2. Which pair of equations does NOT have a common solution?
a) x+y = -1; 4x-3y=24
b)4x+6y=12; 6x+9y=12
c) 2x-3; 2x+y=4
d) 5x-4y=9; x-2y=-3

You can put this solution on YOUR website!
b) does not, because 4x+6y = 12 is equivalent to 6x+9y = 18, which implies that if there is a common solution, then 18 = 12.

c) (2x-3) is not an equation.
