Question

X + 4 < - 9 x < - 13 how do you solve it?

Answer 1

Did you mean to make the X uppercase and the x lowercase?

Answer 2

And if so, are you solving for X or x?

Answer 3

x

Answer 4

Ok. In that case, divide everything by -9:

\begin{align}
X + 4 &< - 9 x &< - 13\\\\
\frac{X + 4}{-9} &< \frac{-9x}{-9} &< \frac{-13}{-9}\\
\end{align}

Because you're dividing by a negative, you need to flip the inequality, so the <s become >s:

\[\frac{X+4}{-9} > x > \frac{13}{9}\]
