    Solve 5 over x plus 8 equals 3 over x for x and determine if the solution is extraneous or not. x = 12, non-extraneous x = 12, extraneous x = -12, non-extraneous x = -12, non-extraneous

    substitute x value into original question to check if it's an extraneous or not if both sides are equal then nope if both sides are not equal then yes it's an extraneous
