tolong gusy... perlu bantuannih nomor 1 sampai nomor 3

No. 2

(x+2/3)- (y+3/2)
= (2x + 4/6) - (3y+9/6)
= 2x - 3y - 5 = 6

Jadi, 2x - 3y = 11

(2+x/2) + (2y+5/3)
= (6 + 3x/6) + (4y + 10/6)
= 3x + 4y + 16 = 24

Jadi, 3x + 4y = 8

2x - 3y = 11. X3. 6x - 9y = 33
3x + 4y = 8. X2. 6x + 8y = 16
y = -1

2x + 3 = 11
2x = 8
x = 4

Maka x - y = 4 - (-1)
= 5
