Answer:

C) -5

Step-by-step explanation:

-1 4/5 x= 9.

Change the left side to an improper fraction

(5*1+4)/5 = 9/5

-9/5 x =9

Multiply each side by -5/9 to isolate x

-5/9 * 9/5x = 9 * (-5/9)

x = -5

Answer:

Step-by-step explanation:

hello

$2x+2=6 2x+2-2=6-2 \ \ \ substract \ \ 2\\ 2x = 4 \dfrac{2x}{2}=x=\dfrac{4}{2}=2 \ \ \ divide \ \ by \ \ 2\\$

so the solution is 2

$5x+4=8 5x+4-4=8-4 \ \ \ substract \ \ 4\\ 5x = 4 \dfrac{5x}{5}=x =\dfrac{4}{5} \ \ \ divide \ \ by \ \ 5$

so the solution is 4/5

hope this helps
