Tentukan penyelesaian dari setiap pertidaksamaan berikut 1. 2(4-3n) <(n-5) 2. 1/6 (6y+8)> 1/2 (5y+12) 3. 3/4 (4p-12) > 2/3 (2p+6)

1.
2(4-3n) < (n-5)
8 -6n < n-5
-6n-n < -5-8
-7n < -14
n > -14/-7
n> 2
HP : {x| x > 2}

2.
(1/6)(6y+8) > (1/2)(5y+12)
y + (8/6) > (5/2)y + 6
y - (y - (5/2)y > 6-(8/6)
y - (5/2)y > 6-(4/3)
(-3/2)y > (14/3)
y < (14/3)÷(-3/2)
y < (14/3) × (-2/3)
y < -38
HP: {y| y < -38}

3.
(3/4)(4p-12) > (2/3)(2p+6)
3p - 9 > (4/3)p + 4
3p - (4/3)p > 4+9
(5/3)p > 13
p > 13÷(5/3)
p> 13×(3/5)
p> 39/5
HP : {p| p> 39/5}

semoga membantu
