Question

What is the solution for this inequality?

Answer 1

-10x<40
divide both sides with -10
x>-4
sign changes since it's divided with negative number

Answer 2

For this case we have the following expression:

$-10x$

We must clear the x:

The -10 that multiplies the x, must be passed to the other side of the inequality, in the form of division. It should be noted that the sense of inequality changes because the number is negative. So, we have left:

$x> \frac{40}{-10}$

Dividing we have:

$x> -4$
