tolong jawab ya makasihh

Misal :
x + 1 = a
y - 3 = b
z + 2 = c

Maka

2/a + 2/b + 3/c = 2
4/a + 3/b+ 3/c = 2
————————— —
-2/a - 1/b = 0
————— *3
-6/a - 3/b = 0..(pers.1)

2/a + 2/b + 3/c = 2
—————————— * 2
4/a + 4/b + 6/c = 4
-4/a + 1/b + 6/c = 5
—————————— —
8/a + 3/b = -1 (pers.2)

Eliminasi pers 1 dan 2

-6/a - 3/b = 0
8/a + 3/b = -1
——————— +
2/a = -1
a = -2
x + 1 = - 2
x = -3

Subs nilai a
-6/a + 3/b = 0
-6/-2 + 3/b = 0
3/b = -3
b = -1
y-3 = -1
y = 2

Subs nilai a dan b :
2/a + 2/b + 3/c = 2
2/-2 + 2/-1 + 3/c = 2
-1 - 2 + 3/c = 2
3/c = 5
c = 3/5
z + 2 = 3/5
z = 3/5 - 10/5
z = -7/5

HP = {(x,y,z)} = {(-3,2,-7/5)}
