{tex} Given\:pair\:of\: equations:\\\frac{x}{7}+\frac{y}{3}=5{/tex}

{tex}\implies \frac{y}{3}=5-\frac{x}{7}\:---(1){/tex}

{tex}and\:\frac{x}{2}-\frac{y}{9}=6{/tex}

{tex}\implies \frac{x}{2}-\frac{y}{3}\times \frac{1}{3}=6\:---(2){/tex}

{tex}substitute \:(1)\:in \: equation\:(2),\: we\:get{/tex}

{tex}\implies \frac{x}{2}-(5-\frac{x}{7})\times \frac{1}{3}=6\:---(2){/tex}

{tex}\implies \frac{x}{2}-\frac{5}{3}+\frac{x}{21}=6{/tex}

{tex}\implies \frac{x}{2}+\frac{x}{21}=6+\frac{5}{3}{/tex}

{tex}\implies \frac{21x+2x}{42}=\frac{18+5}{3}{/tex}

{tex}\implies \frac{23x}{42}=\frac{21}{3}{/tex}

{tex}\implies x = \frac{23}{3}\times \frac{42}{23}{/tex}

{tex}\implies x = 14\:--(3){/tex}

{tex}put \: x=14 \: in \: equation \:(1),\\we\:get{/tex}

{tex}\frac{y}{3}=5-\frac{14}{7}{/tex}

{tex}\implies \frac{y}{3}=5-2{/tex}

{tex}\implies y = 3\times 3 = 9{/tex}

Therefore,

{tex}x = 14 , \: y = 9{/tex}

Arpita Panda 5 years, 5 months ago

Let take 2√ 3/5 is rational no. Then we can write that 2√3/5=r/s where r and s are integers and s not equal to 0. Then r and s has common factor other than 1. =>2√3/5 = a/b => 2√3=5a/b =>√3=5a/b*1/2 =>√3=5a/2b(here 5a and 2b are integers as a and b are the common factor other than 1 so 5a and 2b are also integers) But this contradicts the fact that √3 is irrational . This problem arisen because of our assumption so our assumption is wrong . Hence,we conclude that 2√3/5 is irrational no.
