Question 1024746
Let {{{ x }}} = the unknown number
{{{ (( 63 - x )) /4 = 2x }}}
Multiply both sides by {{{ 4 }}}
{{{ 63 - x = 8x }}}
Add {{{ x }}} to both sides
{{{ 63 = 9x }}}
Divide both sides by {{{ 9 }}}
{{{ 7 = x }}}
----------
The unknown number is 7
----------
check answer:
When a number is subtracted from 63
{{{ 63 - 7 = 56 }}}
and the result is divided by 4
{{{ 56/4 = 14 }}}
The answer obtained is twice the original number
{{{ 14 = 2*7 }}}
OK
