From the text of the task we can write the following equation:

\frac{2x}{5}+\frac{x}{3}=22\\
\\
Solving: multiplying \ all \ terms \ by \ 15:\\
\\
6x+5x=330\\
\\
11x=330\\
\\
x=\frac{330}{11}\\
\\
\boxed{x=30}

<u>2/5 x + 1/3 x = 22</u>

First of all, I've been answering so many of these things lately that I'm
getting really tired of 'x'.  Let's call the unknown number ' Q ' instead.

<u>2/5 Q + 1/3 Q = 22</u>

Multiply each side by 5 :

2Q + 5/3 Q = 110

Multiply each side by 3 :

6Q + 5Q = 330

Add the like terms on the left side:

11Q = 330

Divide each side by 11 :

<u>Q = 30</u> .

Murrr4er [49]

Answer:

-24

Step-by-step explanation:

I´m guessing by the big x sign you want me to multiply so the first step in the equation is to multiply because of PEMDAS so(6*2)+(8*-3)-3*2-6,

so 6*2=12,8*-3=-24,-3*2=-6

12+-24-6-6,

12-24=-12,-6+-6=-12

-12+-12=-24

B. Is the right answer

First you have to take the common elements then use an identity/formula to get the rest

x^3 - 3x^2 + x-3
x^2 (x-3) +1 (x-3)
(x^2 +1) (x-3)
(x-1)(x+1)(x-3) {using a^2-b^2 on x^2-1^2}
