Got this problem on a test:
          ____
12 + √2x-1 = 4

Okay, so then I subtract 12 from both sides:
  ____
√2x-1 = -8
2x - 1 = 64   I then square both sides...
2x = 65        Add 1 to each side
x = 65/2       Divide both sides by two.

However, that answer doesn't work. Are there simply no solutions, then?
