Question

7x - 5 by 2 x =3 solve the following ​

Answer 1

Answer:

$\dfrac{7x-5}{2x}=3\quad :\quad x=5$

Step-by-step explanation:

$\dfrac{7x-5}{2x}=3$

$\mathrm{Multiply\:both\:sides\:by\:}2x$

$\dfrac{7x-5}{2x}\cdot \:2x=3\cdot \:2x$

$\mathrm{Simplify}$

$7x-5=6x$

$\mathrm{Add\:}5\mathrm{\:to\:both\:sides}$

$7x-5+5=6x+5$

$\mathrm{Simplify}$

$7x=6x+5$

$\mathrm{Subtract\:}6x\mathrm{\:from\:both\:sides}$

$7x-6x=6x+5-6x$

$\mathrm{Simplify}$

$x=5$
