Question

Tentukan X dan Y dari persamaan berikut.

y - 12x + 19 = 0 .... (1)
2y = 5x .... (2)

tolong ya.. point

Answer 1

Y - 12x = -19 | x2
2y - 5x = 0 |x1

2y - 24x = -38
2y - 5x = 0
___________-
-19x = -38
x = 2
2y = 5x
y = 5*2/2 = 5

x = 2 dan y = 5

Answer 2

y - 12x + 19 = 0 <= kali 2 semua

2y - 24x + 38 = 0

2y - 5x           = 0

-------------------------- -

     -19x + 38 = 0

    19x = 38

       x = 2

2y - 5x = 0  <= x = 2

2y - 5.2 = 0

2y - 10 = 0

2y = 10

y = 5

Hp : (x,y) = (2,5)
