    Protip: Use (x-2) + (x-1) + x + (x+1) + (x+2)

    Ok, so the left side is 5x + 10 , and that equals 75. What is x?

    No. Isolate the x term, but subtracting 10 from both sides.

    I agree Newton, but ankur had already started in this vein, and it doesn't matter much either way, so long as the method is understood.
