2.tentukan penyelesaian dari persamaan berikut!
a.3(2x-7)=2(x-5)
b.2x+15=-3x
Pakai caraaa yaa!!
Keterangan:x(eks ya) bukan kali
1.penyelesain 5p-4=3p+10 adalah…
1)5p – 4= 3p + 10
5p -3p= 10 + 4
2p = 14
p = 14/2
p = 7
2)a. 3(2x-7) = 2(x-5)
6x – 21 = 2x – 10
6x – 2x = -10 + 21
4x = 11
x = 11/4
b.2x + 15 = -3x
2x + 3x = -15
5x = -15
x = -15/5
x = -3
1. 5p-4 = 3p+10
5p-3p = 4+10
2p = 14
p = 14/2
p = 7
2. a. 3(2x-7) = 2(x-5)
6x-21 = 2x-10
6x-2x = 21-10
4x = 11
x. = 11/4
b. 2x+15 = -3x
2x+3x = -15
5x = -15
x. = -15/5
x. = -3
*maaf kalau salah
