Question

Determine which system below will produce infinitely many solutions. -4x + 6y = 20 4x - 3y = -2 -2x + 4y = 18 4x - 8y = -36 3x - 2y = 5 -6x - 4y = -10 5x - 3y = 12 15x - 9y = 24 can you help me please

Answer 1

The second:

`\left \{ {{-2x+4y=18} \atop {4x-8y=-36}} \right.`
The second equation is equal to the first multiplied by -2, giving two coincident straight lines with infinite points in common (solutions)
