    3 (5x-2) + 4x=9x+6-2x

    3 (5x-2) + 4x=7x+6

    Distributing 3 through parentheses

    3•5x-3•2+4x=7x+6

    15x-3•2+4x=7x+6

    15x-6+4x=7x+6

    19x-6=7x+6 substract 7x

    -7x - 7x

    19x-6-7x=6

    12x-6=6 add 6

    +6 + 6

    12x=6+6

    12x=12 divide by 12

    /12 / 12

    x=12/12

    x=1 solved for x
