4(x - 3) - 3(y - 4) = 0
4x - 12 - 3y + 12 = 0
4x - 3y = 0 (1)
5(x - 4) + 2(y + 2) = 0
5x - 20 + 2y + 4 = 0
5x + 2y - 16 = 0
5x + 2y = 16 (2)
(1) x (2) 8x - 6y = 0 (1.1)
(2) x (3) 15x + 6y = 48 (2.1)
(1.1) + 2.1) 23x = 48
x = 48/23
En (1)
4(48/23) - 3y = 0
3y = 192/23
y = 192/(3x23)
y = 64/23
Solución del sistema:
x = 48/23
y = 64/23
