    x = - 2

    Step-by-step explanation:

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

    multiply numbers in parenthesis by 3

    -2x-7=12x+21

    move terms

    -2x-12x=21+7

    subtract - 2x to - 12x but since there negative the equation is addition. Also, add 21 to 7

    -14x=28

    divide both sides by - 14

    x = - 2
