(b)  $17y,\frac{y}{17},5z$

(c)  $2y+17,2y-17$

(d)  $7m,-7m+3,-7m-3$

Views

(a)   $z+1\rightarrow addition$                                         $y-17\rightarrow subtraction$

$z-1\rightarrow subtraction$                                     $y+17\rightarrow addition$

(b)  $17y\rightarrow multiplication$                       $\frac{y}{17}\rightarrow division$

$5z\rightarrow multiplication$

(c)  $2y+17\rightarrow multiplication \, \, and\, \, \, addition$

$2y-17\rightarrow multiplication \, \, and\, \, \, subtraction$

(d)  $7m\rightarrow multiplication$

$-7m+3\rightarrow multiplication\, \, and\, \, addition$

$-7m-3\rightarrow multiplication\, \, and\, \, subtraction$
