    Let's solve your equation step-by-step.

    3x+6=x9

    Step 1: Cross-multiply.

    3x+6=x9

    (3) * (9) = x * (x+6)

    27=x2+6x

    Step 2: Subtract x^2+6x from both sides.

    27 - (x2+6x) = x2+6x - (x2+6x)

    -x2-6x+27=0

    Step 3: Factor left side of equation.

    (-x+3) (x+9) = 0

    Step 4: Set factors equal to 0.

    -x+3=0 or x+9=0

    x=3 or x=-9
