Método de igualación - x + 2y = 42x - 4y = 3?
Método de igualación - x + 2y = 4 2x - 4y = 3.
En resumen
- 0 + 2y = 4 0 + = 0 - 2y 0 = 0 - 2y = 0 2x - 4y = 3 2x = - 2 + 4yx = + 2 + 4y = 2 x - 2 = x = + 2 + 4 = 2 (x - 2y)x = 2( + 2 + 4y) 0 - xy = + 4 + 8y 0y - 8y = + x + 4 = 8y = + 4y + 4 = 8 0x - 2y(2, 0) = 4 0x - 4, 0 = 4 mcm = 0 0x - 4 = 0 = 0x = 0 - 4 = 0 - 4 + 4 = 0.
