Answer:

-19

37

Step-by-step explanation:

For the first problem, plug in -3 wherever you see the variable 's'.

9*(-3) - 7 - 5*(-3)

= -27 - 7 - (-15)

= -34 + 15 (two negatives together make a positive)

= -19

Similarly, for the second problem, plug in 4 wherever you see an 'n'.

7 - (4÷2) + (8*4)

=7 - 2 + 32

=37
