1) 4x - 3y = 8
2) 3x - 2y = 23
Despejo x en 1
4x - 3y = 8
4x = 8 + 3y
x = (8 + 3y)/4
Sustituyo x en 2
3x - 2y = 23
3 (8 + 3y)/4 - 2y = 23
(9y + 24 - 8y) = 23 (4)
9y + 24 - 8y = 92
y = 92 - 24
y = 68
Sustituyo el valor de y en el despeje de x
x = (8 + 3y)/4
x = (8 + 3 (68)/4
x = (8 + 204)/4
x = 212/4
x = 53
Solución :
x = 53
y = 68
