  1. - 5 g - 6

    g = - 2

    - 5 * ( - 2 ) - 6 = 10 - 6 = 4



    the sum of 3 coins and c coins =

    3 + c = c + 3



    x - 2 = 16 Add 2 to both sides

    x - 2 + 2 = 16 + 2

    x = 18



    z / - 12 = - 5 Multiply both sides by - 12

    z * ( - 12 ) / - 12 = - 5 * - 12

    z = 60



    x - 8.1 = 5.3 Add 8.1 to both sides

    x - 8.1 + 8.1 = 5.3 + 8.1

    x = 13.4

    x = 13 to the nearest whole number



    14 = t - 44 Add 44 to both sides

    14 + 44 = t - 44 + 44

    58 = t

    t = 58



    - 30 = j + 50 Subtract 50 to both sides

    - 30 - 50 = j + 50 - 50

    - 80 = j

    j = - 80



    5.8 = z / 2.2 Multiply both sides by 2.2

    5.8 * 2.2 = z * 2.2 / 2.2

    12.76 = z

    z = 12.76



    4 ( 3 x + 2 ) - 2 =

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

    ( 12 x + 8 ) - 2 =

    12 x + 8 - 2 =

    12 x + 6



    20 b - 16 =

    4 * 5 * b - 4 * 4 =

    4 * ( 5 b - 4 )

  3. 2.8 x = - 9.24 Divide both sides by 2.8

    2.8 x / 2.8 = - 9.24 / 2.8

    x = - 3.3
