En resumen
10x + 18y = - 11 2 * 16x - 9x = - 5 10x + 18y = - 11 32x - 18y = - 10 42x = - 21 x = 21 / 42 x = 1 / 2 10(1 / 2) + 18y = - 11 5 + 18y = - 11 18y = - 16 y = - 16 / 18 y = - 8 / 9.
10x + 18y = - 11 2 * 16x - 9x = - 5
10x + 18y = - 11
32x - 18y = - 10
42x = - 21
x = 21 / 42
x = 1 / 2
10(1 / 2) + 18y = - 11
5 + 18y = - 11
18y = - 16
y = - 16 / 18
y = - 8 / 9.
10x + 18y = - 11 2 * 16x - 9x = - 5 10x + 18y = - 11 32x - 18y = - 10 42x = - 21 x = 21 / 42 x = 1 / 2 10(1 / 2) + 18y = - 11 5 + 18y = - 11 18y = - 16 y = - 16 / 18 y = - 8 / 9.
