Question

$$\xi<8\div9\xi$$

Solve for ξ

$\xi <0$

Solution Steps

Subtract $\frac{8}{9}\xi $ from both sides.

$$\xi -\frac{8}{9}\xi <0$$

Combine $\xi $ and $-\frac{8}{9}\xi $ to get $\frac{1}{9}\xi $.

$$\frac{1}{9}\xi <0$$

Product of two numbers is $<0$ if one is $>0$ and the other is $<0$. Since $\frac{1}{9}>0$, $\xi $ must be $<0$.

$$\xi <0$$
