B)z=-62

c) P = 78

D) N=85

5)

6)S = 11

7)m= -24

Answer 2

• x - (13) =28

    x + 13 = 28

    x = 28 - 13

    x = 15

• z + 45 = 17

    z = -17 - 45

    z = 62

• P + (-21) = 57

    P - 21 = 57

    P = 57 + 21

    P = 78

• 66 = n - 19

    n = 66 + 19

    n = 85

• -51 = 5 + (-r)

   -51 + r = 5

    r = 5 + 51

    r = 56

•   s + 25 - 17 = -3

    s - 25 + 17 = 3

    s = 3 + 25 - 17

    s = 11

• m = 11 - 35

    m = -24
