(c) 2 y + 17, 2 y -17

(d) 7 m , - 7 m + 3, - 7 m - 3

Answer 1

(a) z + 1 -->   Addition              z - 1 --> Subtraction

     y + 17 --> Addition              y - 17 --> Subtraction

(b) 17 y --> Multiplication         y/17--> Division

     5z --> Multiplication

(c) 2 y + 17 --> Multiplication and Addition

     2 y - 17  -->Multiplication and Subtraction

(d) 7m ---> Multiplication

     -7 m + 3 --> Multiplication and Addition

     -7 m - 3 --> Multiplication and Subtraction
