Determine which equation has no solution.

8x - 3 = 4x - 3
8x + 5 = 8x - 5
8x - 5 = 8x - 5
4x + 6 = -4x + 2

Determine which equation has an infinite number of solutions.

8x + 5 = 8x - 5
8x - 3 = 4x - 3
4x + 6 = -4x + 2
8x - 5 = 8x - 5

Determine which equation has no solution.

3(2x - 1) = 3(4x - 1)
6(x - 5) = 6(3x - 4)
2(3x + 4) = 3(2x + 3)
3(2x + 6) = 2(3x + 9)
