Igualamos las ecuaciones para encontrar x eliminando y.
2x - 3 x - 3
-------- = -----------
1 2
2 (2x - 3) = 1 (x - 3)
4x - 6 = x - 3
4x - x = - 3 + 6
3x = 3
x = 3/3
x = 1
Reemplazo x = 1 en cualquiera de los despejes de y.
x - 3 1 - 3 - 2
y = --------- = --------- = --------= - 1
2 2 2
Solución :
x = 1
y = - 1
