    Answer: x = 5

    Step-by-step explanation:

    4x+2x=x+x+20

    Collect like terms to a side.

    4x+2x-x-x=20

    Note, the sign in front of x changes from positive to negative because the x crosses the equal sign

    4x+2x-2x=20

    4x=20

    Divide both side by the coefficient of x

    X=5
