Question 1096283
Let {{{ x }}} = the unknown number
Add {{{ 7 }}}
{{{ x + 7 }}}
Double the result
{{{ 2*( x + 7 ) }}}
This equals {{{ 34 }}}
{{{ 2*( x + 7 ) = 34 }}}
---------------------------
Divide both sides by {{{ 2 }}}
{{{ x + 7 = 17 }}}
Subtract {{{ 7 }}} from both sides
{{{ x = 10 }}}
The number is 10
