Question

1.3y=15+6y
2.4p=6=24-2p
3.5p-8=7p+12
4.3(1-k)-14(k-5)=-5
tolong bantu saya bagaimana jalan hasilnya tolong ya.../

Answer 1

1) 3y = 15 + 6y
3y - 6y = 15
-3y = 15
y = - 5

2) 4p + 6 = 24 - 2p
4p + 2p = 24 - 6
6p = 18
p = 3

3) 5p - 8 = 7p + 12
5p - 7p = 12 + 8
- 2p = 20
p = -10

4) 3(1 - k) - 14(k - 5) = - 5
3 - 3k - 14k + 20 + 5 = 0
- 17k = - 28
k = - 28/17
