    x = 133/4 or x = 33.25 decimal

    Step-by-step explanation:

    Solve for x:

    7 - 4 x = - 126

    Subtract 7 from both sides:

    (7 - 7) - 4 x = - 7 - 126

    7 - 7 = 0:

    -4 x = - 7 - 126

    -7 - 126 = - 133:

    -4 x = - 133

    Divide both sides of - 4 x = - 133 by - 4:

    (-4 x) / (-4) = (-133) / (-4)

    (-4) / (-4) = 1:

    x = (-133) / (-4)

    Multiply numerator and denominator of (-133) / (-4) by - 1:

    Answer: x = 133/4
