Question 1152297
Let {{{ x }}} = the unknown number
{{{ 3*( x - 5 ) = 2x + 3 }}}
{{{ 3x - 15 = 2x + 3 }}}
Subtract {{{ 2x }}} from both sides
{{{ x - 15 = 3 }}}
Add {{{ 15 }}} to both sides
{{{ x = 18 }}}
--------------------
check:
{{{ x - 5 = 18 - 5 }}}
{{{ x - 5 = 13 }}}
{{{ 13*3 = 39 }}}
--------------------
{{{ 2*18 = 36 }}}
{{{ 36 + 3 = 39 }}}
OK
