Vamos a resolver la ecuación 7 - |x+3| = 1 .

### Paso 1: Aislar el valor absoluto
Restamos 7 de ambos lados:
7 - |x+3| = 1 \implies |x+3| = 7 - 1.

Simplificamos:
|x+3| = 6.


### Paso 2: Resolver la ecuación del valor absoluto
Sabemos que |x+3| = 6 implica dos casos:
1. x+3 = 6 ,
2. x+3 = -6 .

#### Caso 1: x+3 = 6
Resolviendo para x :
x = 6 - 3 \implies x = 3.


#### Caso 2: x+3 = -6
Resolviendo para x :
x = -6 - 3 \implies x = -9.


### Paso 3: Verificar las soluciones
Las soluciones son x = 3 y x = -9 . Ambas satisfacen la ecuación original.

### Respuesta final:
La solución es:
\boxed{\text{A. Las soluciones son } 3, -9.}
