Question

Tolong no 21-26 pake cara

Answer 1

21 a

22 c
3(x + 2) + 5 = 2(x + 15)
3x + 11 = 2x + 30
x = 19

23 d
3(2p - 2) = 3p + 18
6p - 6 = 3p + 18
3p = 24
p = 8

24 b
3/4(x + 8) = 1/2(x - 4) --> kali 4
3(x + 8) = 2(x - 4)
3x + 24 = 2x - 8
x = -32

25 d
2(2a - 3) > 3(2a + 4)
4a - 6 > 6a + 12
-18 > 2a
-9 > a
a < -9

26 a
2x - 3 > atau = 5
2x > atau = 8
x > atau = 4
