5x = 1612x - 20 = 03x ^ 2 = 273y - 2 = 7 - y - 8z + 4 = - 5 + 10z?

5x = 16 12x - 20 = 0 3x ^ 2 = 27 3y - 2 = 7 - y - 8z + 4 = - 5 + 10z.

En resumen

5x = 16 x = 16 / 5 3x ^ 2 = 27 x ^ 2 = 27 / 3 x ^ 2 = 9 x = + / - √9 x = + / - 3 ó x1 = 3 ; x2 = - 3 3y - 2 = 7 - y 3y + y = 7 + 2 4y = 9 y = 9 / 4 - 8z + 4 = - 5 + 10z 4 + 5 = 10z + 8z 9 = 18z z = 9 / 18 z = 1 / 2.

5x = 16 x = 16 / 5

3x ^ 2 = 27 x ^ 2 = 27 / 3 x ^ 2 = 9 x = + / - √9 x = + / - 3 ó x1 = 3 ; x2 = - 3

3y - 2 = 7 - y

3y + y = 7 + 2

4y = 9

y = 9 / 4 - 8z + 4 = - 5 + 10z

4 + 5 = 10z + 8z

9 = 18z

z = 9 / 18

z = 1 / 2.
