Question

Tentukan himpunan penyelesaian dari peridaksamaan berikut.
2/3p+4≤8

Answer 1

2/3p+4 ≤ 8
2/3p+12p/3p ≤ 8
2+12p ≤ 8 x 3p
2+12p ≤ 24p
2 ≤ 24p-12p
2 ≤ 12p
1 ≤ 6p
maka, himpunan penyelesaiannya => p ≥ 1/6

Answer 2

2/3p+4 ≤ 8
2/3p ≤ 8-4
2/3p ≤ 4
2p ≤ 4×3
2p ≤ 12
p ≤ 12/2
p ≤ 6

hasilnya p ≤ 6
