sistem persamaan linear dua variabel[tex] \frac{x-1}{6} + y =6 x+ \frac{y-1}{4} =8[/tex]

jawab
(x-1)/6  + y = 6  } kali 6
x - 1 + 6y = 36
x + 6y = 37

x + (y -1)/4  =8  } kali 4
4x + y - 1= 32
4x + y = 33

x + 6y = 37 } kali 4
4x + y = 33

4x + 24 y = 148
4x + y = 33  | (--)
23 y = 115
y = 5

4x + y = 33
4x + 5 = 33
4x = 28
x = 7

(x,y)= (7,5)
