<h3>Given Equation:-</h3>

$\boxed{ \tt \frac{3}{x + 5} - \frac{2}{x - 3}}$

<h3>Step by step expansion:</h3>

$\dashrightarrow\sf\dfrac{3}{x + 5} - \dfrac{2}{x - 3}$

Write the equation

$\\ \\$

$\dashrightarrow\sf\dfrac{\frac{3 \times (x + 5)(x - 3)}{x + 5} - \frac{2 \times (x + 5)(x - 3)}{x - 3}}{(x + 5)(x - 3)}$

Take the lcm of the equation I.e (x + 5) (x + 3)

$\\ \\$

$\dashrightarrow\sf\dfrac{\frac{3 \times \cancel{(x + 5)}(x - 3)}{\cancel{x + 5}} - \frac{2 \times (x + 5)\cancel{(x - 3)}}{\cancel{x - 3}}}{(x + 5)(x - 3)}$

cancel like terms I.e (x + 5) with (x+ 5) and (x - 3) with (x - 3)

$\\ \\$

$\dashrightarrow\sf\dfrac{\frac{3 \times (x - 3)}{1} - \frac{2 \times (x + 5)}{1}}{(x + 5)(x - 3)}$

$\\ \\$

$\dashrightarrow\sf\dfrac{3 \times (x - 3)- 2 \times (x + 5)}{(x + 5)(x - 3)}$

Remove 1 as denominator

$\\ \\$

$\dashrightarrow\sf\dfrac{3x - 9- 2 (x + 5)}{(x + 5)(x - 3)}$

Multiply 3 with x - 9

$\\ \\$

$\dashrightarrow\sf\dfrac{3x - 9- 2 x - 10}{(x + 5)(x - 3)}$

Multiply - 2 with x + 5

$\\ \\$

$\dashrightarrow\sf\dfrac{3x - 2x- 9 - 10}{(x + 5)(x - 3)}$

Arrange the equation so that it would be easier to solve.

$\\ \\$

$\dashrightarrow\sf\dfrac{x- 9 - 10}{(x + 5)(x - 3)}$

Subtract 3x with 2x

$\\ \\$

$\dashrightarrow\bf\dfrac{x-19}{(x + 5)(x - 3)}$

Add -9 with - 10

$\\ \\$

$\therefore \underline {\textsf{\textbf{Option \red{one} is correct}}}$

A company has two types of machines, type R and type S. Operating at a constant rate, a machine of type R does a certain job in

SashulF [63]

Answer:

The number of machines to complete job in 2 hours is 6.

Step-by-step explanation:

Using the relation of the rate of each one machine and knowing that adding up both rates.

$Rate R +Rate S= Rate total$

Rate R = $\frac{x}{36}$ 'x' is the job

Rate S = $\frac{x}{18}$ 'x' is the job

So, using the equation of rates

$Rate total =\frac{x}{36} + \frac{x}{18}$

Rate total is going to be a job in 2 hours so = $\frac{1}{2}$

$\frac{1}{2} = \frac{x}{36}+\frac{x}{18}$ <em>adding up</em>

$\frac{1}{2}= x*\frac{3}{36}$ <em>factoring the x</em>

$\frac{1}{2}= x*\frac{1}{12}$ <em>simplifying</em>

x= $\frac{12}{2} \\$

x= 6

Solve 6(x + 1) > 2x - 1

marissa [1.9K]

Answer:

x>-7/4

Step-by-step explanation:

6(x+1)>2x-1

Solve for x:

$6x+6>2x-1\\\\6x-2x+6>2x-2x-1\\\\4x+6>-1\\\\4x+6-6>-1-6\\\\4x>-7\\\\x>-\frac{7}{4}$
