Answer:

$\boxed{\sf x=2}$

Step-by-step explanation:

$\sf 2x+5=9$

<u>Subtract 5 from both sides.</u>

<u /> $\sf 2x+5-5=9-5$ <u />

<u /> $\sf 2x=4$ <u />

<u>Divide both sides by 2.</u>

$\sf \cfrac{2x}{2}=\cfrac{4}{2}$

$\sf x=2$

Solve the inequality for x: -5x - 49 > 113

Valentin [98]

-5x - 49 > 113
Add 49 to both sides
-5x > 162
Divide both sides by -5
x > -32.4
Hope this helps!
