    x = 6

    Step-by-step explanation:

    Pull out like factors:

    -4x - 13 = - 1 • (4x + 13)

    Equation at the end of step 2:

    -178 - (-5x + - 4 • [4x + 13]) = 0

    Pull out like factors:

    21x - 126 = 21 • (x - 6)

    Equation at the end of step 4:

    21 • (x - 6) = 0

    Solve:

    x-6 = 0

    Add 6 to both sides of the equation:

    x = 6
