    If this is a simultaneous equation then:

    you should simplify it to get 18+2x=-8x+42+18x

    Then simplify again and you get: 18+2x=10x+42

    Next if you minus 2x from both sides you get: 18=8x+42

    After that you minus 42 from both sides to get: - 24=8x

    Finally, divide both sides by 8 and you get: - 3=x
