5(p-3)-2(p-3)=9 berapa nilai p?? Pakai cara 3x+2<5x-11 berapa nilai x?? Pakai cara 3x-5>2x+3 berala nilai x?? Pakai cara 5x-1 krang dri sama dgn x+2 nilai x?? P

a) 5(p-3)-2(p-3) = 9
5p -15 -2p +6 = 9
5p -2p = 9 +15-6
3p = 18
p = 18/3
p = 6
b) 3x +2 < 5x -11
3x -5x < -11 -2
-2x < -13 ( kalikan dg -1/2)
x > 13/2
c) 3x -5 > 2x +3
3x -2x > 3 +5
x > 8
d) 5x - 1 <= x + 2
5x - x <= 2 + 1
4x <= 3
x <= 3/4 ( <= adalah kecil atau sama)
e) 1/2(x + 1) + 3 = 2/3x + 3
1/2x + 1/2 + 3 = 2/3x + 3
1/2x - 2/3x = 3 -3 -1/2
3/6x - 4/6x = -1/2
-1/6x = -1/2 (kalikan dg -6 )
x = 3
f) 14/3x -4 1/3x +2/6 = 5 1/8
(14/3)x - (13/3)x = 41/8 - 2/6
(1/13)x = 123/24 - 8/24
(1/13)x = 115/24 ( kalikan dg 13)
x = (115/24)×13..silahkan lanjutkan...!
g) 2x - 1/3 +6x +4/2 = 4x + 3
2x +6x -4x = 3 -2 + 1/2
4x = 1 + 1/2
4x = 3/2 ( kalikan dg 1/4)
x = (3/2)×4
x = 6.
