Question

comprobación de 2x/3 + x = 10/3

Answer 1

Comprobación de 2x/3 + x = 10/3

2x/3 + x = 10/3(x * 3 + 2x)/3 = 10/3
(3x + 2x)/3 = 10/3
5x/3 = 10/3
3 (5x) = 3 (10)
15x = 30
x = 30/15
x = 2

Rpt. El valor de x es 2


COMPROBAMOS LA SOLUCIÓN.
2x/3 + x = 10/32 (2)/3 + 2 = 10/3
4/3 + 2 = 10/3
(3 * 2 + 4)/3 = 10/3
(6 + 4)/3 = 10/3
10/3 = 10/3

LISTO!

Answer 2

2x/3 + x = 10/3
x= 10/3-2x/3
x=(10-2x)/3
3x=10-2x
3x+2x=10
5x=10
x=10/5
x=2

reemplazamos
2(2)/3 + (2)= 10/3
4/3 + 2 =10/3
(4+3(2))=10/3
(4+6)/3=10/3
10/3=10/3
