1. 2x+4>6+4x
2x-4x>-4+6
-2x>2
x<-1

2. 2x-3<7
2x<10
x<5

3. 2(3p-4)=4p+6
6p-8=4p+6
2p=14
p=7

4. 4x+5=3x+9
x=4

5. 6x-5=4x-15
2x=-10
x=-5

Nomor 6 aneh, masa nanti variabel y-nya habis=_=

1. 2x + 4 > 6 + 4x 2x + 4 - 4 > 6 - 4 + 4x 2x > 2 + 4x 2x - 4x > 2 + 4x - 4x -2x > 2 -2x ÷ -2 < 2 ÷ -2 (kalau di bagi bilangan negatif, tanda di balik) x < 1 2. 2x - 3 < 7 2x - 3 + 3 < 7 + 3 2x < 10 x < 5 3. 2(3p - 4) = 4p + 6 6p - 8 = 4p + 6 6p - 8 + 8 = 4p + 6 + 8 6p = 4p + 14 6p - 4p = 4p - 4p + 14 2p = 14 p = 7 4. 4x + 5 = 3x + 9 4x + 5 - 5 = 3x + 9 - 5 4x = 3x + 4 4x - 3x = 3x - 3x + 4 x = 4 5. 6x - 5 = 4x - 15 6x - 5 + 5 = 4x - 15 + 5 6x = 4x - 10 6x - 4x = 4x - 4x - 10 2x = -10 x = -5 Maaf kalau salah.. Semoga membantu..
3. p = 7
4. x = 4
5. x = -5
Oh iya, no. 6 y nya habis.. saya bingung..
maaf baru jawab
