Bagaimana cara dan jawabanya

2x+3y=10
3x+y=8

Answer 1

Dengan cara eliminasi:
2x +3y = 10} x1
3x + y  =   8} x3

2x + 3y =10
9x + 3y = 24
___________ -
-7x        = -14
x           = -14 : -7 = 2


y = 2x + 3y = 10
   = 2(2) + 3y = 10
   = 4 + 3y = 10
3y = 10 - 4
     = 6
y   =  6 : 3 = 2


Selesai. Sorry kalau salah
