Question

1. 1/5 ( x + 3 ) = 4. Nilai dari x + 10 adalah....?
2. 3 ( p + 5 ) - 2 ( p + 3 ) = 18. Maka nilai p adalah...
3. 5 ( 2 x + 4 ) = 2 ( 4 x - 6 ) maka nilai dari 2 x + 8 adalah...
Pakai Caranya ya ! :D

Answer 1

1. 1/5x + 3/5 = 4
     1/5x = 4 - 3/5
   1/5x = 17/5
   x = 17/5 : 1/5 = 17/5 x5/1 =17
2. 3p + 15 - 2p + 6 = 18
   3p - 2p = 18 - 15 - 6
   p = -3
3. 10x + 20 = 8x - 12
     10x - 8x = -12 - 20
     2x = -32
     x= -32 : 2 = -16

Answer 2

Nomor 1
1/5(x+3) = 4
____________ x5 (dikali 5 agar pecahannya habis)

x+3 = 5.4
x+3=20
x=20-3
x=17
Maka >> x+10 = 17+10 = 27

Nomor 2
3(p+5)-2(p+3)=18
3p+15-2p-6=18
3p-2p+15-6=18
p + 9 = 18
p = 18-9
p = 9

Nomor 3
5(2x + 4) = 2(4x - 6)
10x + 20 = 8x - 12
10x - 8x = -12 - 20
2x = -32
x = -32 : 2
x = -16
Maka >> 2x + 8 = 2(-16) + 8 = -32 + 8 = -24
