Answer:

x = - $\frac{14}{3}$

Step-by-step explanation:

Given

$\frac{6x+3}{5}$ = 3x + 9 ( multiply through by 5 to clear the fraction )

6x + 3 = 15x + 45 ( subtract 15x from both sides )

- 9x + 3 = 45 ( subtract 3 from both sides )

- 9x = 42 ( divide both sides by - 9 )

x = $\frac{42}{-9}$ = - $\frac{14}{3}$

What is the difference A B C D

aksik [14]

Answer:

D. $\frac{x-1}{x^2+3x+2}}$

Step-by-step explanation:

The given expression is;

$\frac{x}{x^2+3x+2}-\frac{1}{(x+2)(x+1)}$

This is the same as;

$\frac{x}{(x+2)(x+1)}-\frac{1}{(x+2)(x+1)}$

The denominators are the same.

Subtract the numerators and write one denominator;

$\frac{x-1}{(x+2)(x+1)}}$

Rewrite to get;

$\frac{x-1}{x^2+3x+2}}$
