Pertanyaan

tentukan nilai n,jika n anggota himpunan bilangan bulat :

a.p+2q= -8
b.13+(-2n)=8

Answer 1

1.
p + 2q = -8
p = -8 - 2q
p = -8 - 2q, q € R

2.
13 + (-2n) = 8
13 - 2n = 8
-2n = 8-13
-2n = -5
n = 5/2

maaf kalau salah

Answer 2

13 + (-2n) = 8
-2n = 8 - 13
-2n = -(13-8) = -5
n = -5/-2
n = 2½
