PACHECOCAPB



TU respuesta es

Answer 2

5/3 (7x - 2) = 10
5 (7x - 2) = 10 (3)
35x - 10 = 30
35x = 30 + 10
35x = 40
x = 40/35
x = 8/7

Rpt. El valor de x es 8/7


COMPROBAMOS LA SOLUCIÓN.
5/3(7x-2)=10
5/3 (7 * 8/7 - 2) = 10
5/3 (56/7 - 2) = 10
5 (56/7 - 2) = 3 (10)
5 (7 * - 2 + 56)/7 = 30
5 (- 14 + 56)/7 = 30
5 (42)/7 = 30
210/7 = 30
30 = 30

Listo!
