tolung pecahkan masalahnya dong kk

2x3-4/-1=10
2x3+2/-1=4
3-(-1)= 4

2p - 4/l = 10 .==» ( 2pl -4)/ l = 10
2pl - 4 = 10l. ==» 2pl = 10l + 4....1)
2p + 2/l = 4. ==» (2pl + 2)/ = 4.
2pl +2 = 4l. ==» 2pl = 4l - 2.....2)
..1) dan..2)
10l + 4 = 4l - 2
10l - 4l = -2 - 4
6l = -6
L = -1
2pl = 4l - 2
-2p = 4.-1 -2
-2p = -4 - 2
-2p = -6
p = 3
Jadi p - l = 3- -1 = 3 + 1 = 4
perempuan = 3, lelaki = -1
