Answer 1

Answer:

Step-by-step explanation:

16.             LHS                           RHS

             2 - ( 5 - 4)                 ( 2 - 5 ) - 4

             2 - 1                           ( -3 ) - 4

                               1   $\neq$  ( -7 )

17. let the other integer be x

    ( -12 ) + x = 14

    x = 14 + 12

    x = 22

18. Let the number be x

     ( -45 ) - x = 10

     -x = 10 + 45

     -x = 55

      x = (-55)
