Answer:

x = - \frac{29}{7}

Step-by-step explanation:

\frac{x+1}{4} + \frac{x+2}{2} = \frac{x-3}{2} - \frac{x-1}{3}

Multiply through by 12 ( the LCM of 4, 2, 3 ) to clear the fractions

3(x + 1) + 6(x + 2) = 6(x - 3) - 4(x - 1) ← distribute parenthesis on both sides

3x + 3 + 6x + 12 = 6x - 18 - 4x + 4 , that is

9x + 15 = 2x - 14 ( subtract 2x from both sides )

7x + 15 = - 14 ( subtract 15 from both sides )

7x = - 29 ( divide both sides by 7 )

x = - \frac{29}{7}

Answer:

Well do you know the butterfly method

you multiply 2 by x+1 and 4 by x + 2

Step-by-step explanation:

2(x+1) + 4(x+2) = 3(x-3) -2(x - 1)

2x + 2 + 4x + 8 = 3x - 9 - 2x + 2

2x + 4x +8 = 3x - 2x -9 +2

6x + 8 = x -7

6x - x = -7 -8

5x = -15

x = -15/5

x = -3

Find f(5) please explain
kirza4 [7]

Answer:

-1

Step-by-step explanation:

A function is represented by the following symbol f(x) where f(x) further represents y like this ,

y=f(x)

so in this question they are asking what is f(5) which means when the value of x is 5 what is the value of y?

We can see in the graph when x = 5 the value of y is -1 to be exact so

f(5) = -1

or

y=f(x)\\-1 = f(5)\\

Solve for x: 5/x^2-4+2/x=2/x-2
IRINA_888 [86]

\dfrac{5}{x^2 - 4} + \dfrac{2}{x} = \dfrac{2}{x - 2}


\dfrac{5}{(x + 2)(x - 2)} + \dfrac{2}{x} = \dfrac{2}{x - 2}


\dfrac{5}{(x + 2)(x - 2)} \times x(x + 2)(x - 2) + \dfrac{2}{x} \times x(x + 2)(x - 2) = \dfrac{2}{x - 2} \times x(x + 2)(x - 2)


5x + 2(x + 2)(x - 2) = 2x(x + 2)


5x + 2(x^2 - 4) = 2x^2 + 4x


5x + 2x^2 - 8 = 2x^2 + 4x


5x - 8 = 4x


x - 8 = 0


x = 8


Now we look at the common denominator.

It is x(x + 2)(x - 2).

x cannot be zero, -2 or 2 because that would cause a zero in the denominator.

Since we get x = 8, and x = 8 does not have to be excluded from the domain, the answer is x = 8.
