    Answer:

    x = -1

    Step-by-step explanation:

    3x+2(x-9)=8x+x-14 ;; equation

    simplify the equation to the form

    3x+2(x-9)=8x+x-14

    reorder the terms in parentheses

    3x+(+2x-18)=8x+x-14

    remove unnecessary parentheses

    +3x+2x-18=+8x+x-14

    move all terms containing x to the left and all other terms to the right.

    +3x+2x-8x-1x=-14+18

    simplify left and right side of the equation.

    -4x=+4

    divide both sides of the equation by -4 to get x.

    x=-1
