If you would like to evaluate - 3 + y / 5 when y = - 2.5, you can calculate this using the following steps:

- 3 + y / 5 = - 3 + (- 2.5) / 5 = - 3 - 0.5 = - 3.5 = - 7/2

The correct result would be - 3.5.

If you would like to evaluate (- 3 + y) / 5 when y = - 2.5, you can calculate this using the following steps:

(- 3 + y ) / 5 = (- 3 + (- 2.5)) / 5 = - 5.5 / 5 = - 1.1

The correct result would be - 1.1
When we have the value for the variable, all we have to do is apply the number to replace the variable, then solve.

-3+y/5 will turn into :-   -3+-2.5              -5.5
                               ------------------ =   -------------= -1.1
                                        5                        5


Now we need to divide -5.5 by 5. We get -1.1


Our final answer: -1.1
