$x:(x+4) = 3:5\\\\\implies \dfrac x{x+4} = \dfrac 35 \\\\\implies 5x = 3x +12\\\\\implies 5x -3x = 12\\\\\implies 2x = 12\\\\\implies x = \dfrac{12}2 = 6$

Answer:

X=6

Step-by-step explanation:

X divided by(x+4)=3 divided by 5, x=-4

cross multiply

5x=3(x+4)

Remove parentheses

5x=3x+12

move the variable to the left

5x-3x=12

collect like terms

2x=12

divide both sides

x=6

Answer:

$\implies \dfrac{ -4x+7}{2(x-2) }$

Step-by-step explanation:

The given expression to us is ,

$\implies \dfrac{\frac{ 3}{x-1} -4 }{ 2 -\frac{2}{x-1}}$

Now take the LCM as ( x - 1 ) and Simplify , we have ,

$\implies \dfrac{\frac{ 3 -4(x-1) }{x-1} }{ \frac{2-2(2x-1)}{x-1}}$

Simplifying further , we get ,

$\implies \dfrac{ -4x+7}{2(x-2) }$

Hence the second option is correct .
