a)2m-n
b)3p+n
c)-4n
d)-4n+3m

(justifique com calculos)

Answer 1

m= -4
n= -1
p= -16

Basta substituir as incógnitas..

a)
2×(-4)-(-1)
-8+1
-7
_______________________
b)
3×(-16)+(-1)
-48-1

Forte abraço!

Answer 2

Se m = - 4 , n = -1 , e p = - 16

a) 2m - n =
2 . (-4) - (- 1)=

= - 8 + 1

= - 7

_______________________

b) 3p + n =
3 . (-16) + (-1) =
- 48 - 1
= - 49

______________________

c) - 4n =
- 4 . (-1) =
= 4

______________________

d) - 4n + 3m =
- 4 . (-1) + 3 . (-4) =
4 - 12
= - 8
