tentukan nila x,y,z menggunakan SPLTV 2x+3y+5z = 53 3x+5y+z. = 43 2x+3y+2z = 35

2x+3y+5z= 53
3x+5y+z= 43
2x+3y+2z= 35

2x+3y+5z= 53
2x+3y+2z= 35
___________ -
3z= 18
z= 6

3x+5y+z= 43 x2 6x+10y+2z= 86
2x+3y+5z= 53 x3 6x+9y+15z= 159
_____________ -
y-13z= 73

y-13(6)= 73
y= 151

2x+3y+5z= 53
2x+3(151)+5(6)= 53
2x= -453+53-30
x= -215

maap kalo salah
