Respuesta :
[tex] \frac{x}{7} = - 57 \\ x = - 57 \times 7 \\ x = - 399[/tex]
The answer is -399.
- Simplify both sides of the equation
[tex]\sf \longmapsto \dfrac{1}{7} x = - 57[/tex]
- Multiply both sides by 7
[tex]\sf \longmapsto7* (\dfrac{1}{7} x)=(7)*(−57)[/tex]
[tex]\sf \longmapsto \: x=−399[/tex]
