x/2 + 3y = 1
x + 3y = 1 (2)
1) x + 3y = 2
2) x + 2y = 1
Despejo x en 1
x + 3y = 2
x = 2 - 3y
Sustituyo x en 2
x + 2y = 1
2 - 3y + 2y = 1
- y = 1 - 2
- y = - 1
y = 1
El valor de y sustituyo en el despeje de x
x = 2 - 3y
x = 2 - 3 (1)
x = 2 - 3
x = - 1
Solución :
x = - 1
y = 1
x/2 + 3y = 1
x + 3y = 1 (2)
1) x + 3y = 2
2) x + 2y = 1
Despejo de x en 1:
x + 3y = 2
x = 2 - 3y
Sustituir la x en 2
x + 2y = 1
2 - 3y + 2y = 1
- y = 1 - 2
- y = - 1
y = 1
El valor de y sustituyo en el despeje de x
x = 2 - 3y
x = 2 - 3 (1)
x = 2 - 3
x = - 1
Solución :
x = - 1
y = 1
