5x 1 x 3 x 5 5x 1 40

Asked by admin @ 20/08/2021 in Math viewed by 362 People

(5x-1) (x+3)=(x-5)(5x+1)+40 find the value of x with process

Answered by admin @ 20/08/2021

$\bf{\underline{\huge{ANSWER}}}$

=> (5x - 1 )( x + 3 ) = ( x - 5 ) ( 5x + 1 ) + 40

=> 5x ( x + 3 ) - 1 ( x + 3 ) = x ( 5x + 1 ) - 5 ( 5x + 1 )
+ 40

=> 5x² + 15x - x - 3 = 5x² + x - 25x - 5 + 40

=> 5x² - 5x² + 14x + 24x = 35 + 3

=> 38x = 38

=> x = 38/38

$\bf{=> x = 1}$

$\bf{\underline{ANS}}$

$\bf{\underline{\huge{The \: value \: of \: x \: is \: 1}}}$
