penyelesaian dari 4p+3q=-4,dan 3p-2q=14 adalah x dan y.nilaix-3y=...

4p+3q = -4  [×3]
3p-2q = 14  [×4]

12p+9q = -12
12p -8q =   56    -
17q = -68
q = -68/17
q = -4

subtitusi q = -4
4p+3q = -4
4p+3(-4) = -4
4p-12 = -4
4p = -4+12
4p = 8
p = 8/4
p = 2

p → x = 2
q → y = -4

x-3y = 2-3(-4)
= 2+12
= 14

semoga membantu :)
