Question

Tentukan himpunan penyelesaian dari
4/x -3/y =1
6/x -3/y = 4

bantuin dong ^^

Answer 1

4 / X - 3 / Y = 1
6 / X - 3 / Y = 4


4y - 3x = 1
6y - 3x = 4
+
10y= 5
   y= 1/2

4 × 1/2 - 3x = 1
2 - 3x = 1
-3x = -1
x = 1/3

jadi HP = { 1/3 , 1/2 }

Answer 2

4/x-3/y=1 - 6/x-3/y=4 =(Y habis) -2/x=-3 =(sama sama "-" ☞ "-" hilang) 2/x=3 =(x pindah ruas) 2 = 3x = x = ⅔ Substitusikan x = ⅔ =4/⅔-3/y=1 =12/2-3/y=1 =6-3/y=1 =-3/y=1-6 =-3/y=-5 =3/y=5 =3=5y =y=3/5 Hp : {⅔,3/5}
