Question

Solve $-5(x+4)>30;xϵZ$

Answer 1

-5 (x+4) > 30

$\Rightarrow \frac{-5(x+4)}{-5}<\frac{30}{-5}....(Dividingby-5)$

Note : Division by a negative number reverses the equality

$x+4<-6$

$\Rightarrow x+4-4<-6-4\left(Subtracting4\right)$

$\Rightarrow x<-10$

$\therefore$ Required Answer = {-11, -12, -13,...}
