Mohon tolong di jawab! besok harus di kumpulkan!!! Mohon bantuannya!!

jawab
1,a
(5a +3)/3  - (4a -8)/ 4 = 1 .....kalikan 12
4(5a+3) - 3(4a -8) = 12
20a +12 -12a + 24 = 12
8a + 36 = 12
8a = - 24
a = - 3

1b.
(a+3)/2 - 3 = 1 - a/3 ....kalikan 6
3(a +3) - 18 = 6- 2a
3a + 9 - 18 = 6 - 2a
3a- 9 = 6 - 2a
3a + 2a = 6+9
5a = 15
a= 3

(2) 
2/5 x - 4 = ( x-1)/2.....kalikan 10
4x - 10 = 5(x - 1)
4x - 10 =  5x - 5
4x - 5x = - 5 +10
- x = 5
x = - 5

(3)
4(2x +3)  = 10x + 8
8x + 12 = 10x +8
8 x -10x = 8 -12
-2x = -4
x = 2

4a.
2/3 (y-1) < 1/5 y - 10.....kalikan 15
10(y-1) < 3y - 150
10y -10 < 3y - 150
10y - 3y  < -150 + 10
7y < - 140
y < 20

4b.
1/3 (5p +1) > 1/2 (2p -1) .....kalikan 6
2(5p +1) > 3(2p -1)
10p + 2 > 6p - 3
10p - 6p > -3 -2
-4p > - 5
p < 5/4

5a.
2(p+1) - 4p < 4 - (p-5)
2p + 2 - 4p < 4 - p + 5
-2p + 2 < 9 - p
-2p + p < 9 - 2
-p < 7
p > - 7

5b.
2/3 (3p -9) ≥ 3/4 (4p +8).....kalikan 12
8(3p -9) ≥ 9(4p +8)
24p -72  ≥ 36 p + 72
24p - 36 p ≥ 72 + 72
- 12p ≥ 144
p ≤ 12
