hallar soluciones de |$\frac{3}{7}$x+8|=9

Answer 1

Respuesta:

x = 7 / 3  ||

x = - 119 / 3

Explicación paso a paso:

| 3 / 7 x + 8 | = 9

± ( 3 / 7 x + 8 )  = 9

For " +" :

3 / 7 x + 8 = 9

3 / 7 x = 9 - 8

3 / 7 x = 1

3 x = 7

x = 7 / 3

For " - " :

- 3 / 7 x - 8 = 9

- 3 / 7 x = 17

- 3 x = 119

x = - 119 / 3
