    The steps are the same usually. Remove the brackets and collect like terms on each side of the equal sign.

    Solution

    22+5d = - 8 (7d - 4) Remove the brackets.

    22+5d = - 56d + 32 Notice the sign change on 32. 2 minus quantities = a plus when multiplied. Add 56d to both sides.

    22 + 5d + 56d = - 56d + 56d + 32

    22 + 61d = 32 Subtract 22 from both sides.

    61d = 32 - 22

    61d = 10 Divide by 51

    d = 10/61

    d = 0.1639 Answer

    Check

    LHS

    22 + 5*0.1639 = 22.8197

    RHS

    -8 (7*0.1639 - 4)

    -8 (1.1473 - 4)

    -8 (-2.8527)

    22.8216

    The difference is a rounding error.

    22+5d=-8x7d=56d + - 8x-4=32

    22+5d=-56d+32

    22+32=54 and - 56d+5d=-51d

    The answer would be 51d+54
