1) - x + 5y = 6
2) 3x + y = 10
Despejo y en 2
3x + y = 10
y = 10 - 3x
Sustituyo y en 1
- x + 5y = 6
- x + 5 (10 - 3x) = 6
- x + 50 - 15x = 6
- 17x = 6 - 50
- 16x = - 44
- 16x = - 44
x = -44/-16
x = 11/4
Sustituyo el valor de x en el despeje de y
y = 10 - 3x
y = 10 - 3 (11/4)
y = 10 - 33/4
y = (10 * 4 - 33)/4
y = (40 - 33)/4
y = 7/4
Solución :
x = 11/4
y = 7/4
