Question

(Find the value of x) 5(1-x)+3(1+x)/(1-2x)=8

Answer 1

Step-by-step explanation:

3(1+x)/1-2x = 8-5(1-x)

3+3x/1-2x= 8-5+5x

3+3x/1-2x=3+5x

3+3x=(3+5x)×(1-2x)

3+3x= 3-x-10xsqaure

x=0

Answer 2

The final answer is 4/30.

Step-by-step explanation:

$\ Given \ value:\\\\ 5(1-x)+3(1+x)/(1-2x)=8 \\\\\ Find:\\\\x= ?\\\\\ Solution:\\\\ 5(1-x)+\frac{3(1+x)}{(1-2x)}=8 \\\\\rightarrow \frac{5(1-x)(1-2x)+3(1+x)}{(1-2x)}=8 \\\\\rightarrow \frac{5(1-3x+2x^2)+3+3x)}{(1-2x)}=8 \\\\\rightarrow \frac{5-15x+30x^2+3+3x}{(1-2x)}=8 \\\\\rightarrow \frac{8-12x+30x^2}{(1-2x)}=8 \\\\\rightarrow 30x^2-12x+8=8(1-2x) \\\\\rightarrow 30x^2-12x+8=8-16x \\\\\rightarrow 30x^2-12x+8-8+16x=0 \\\\\rightarrow 30x^2+4x=0 \\\\\rightarrow 30x^2=4x$

$\rightarrow 30x=4 \\\\\rightarrow x=\frac{4}{30}$
