Question 1108800
{{{ -39 = 3*( x - 3 ) - 6x }}}
{{{ -39 = 3x - 9 - 6x }}}
This will look easier if I multiply both sides by {{{ -1 }}}
{{{ 39 = -3x + 9 + 6x }}}
Do the operation on the right side
{{{ 39 = 3x + 9 }}}
Subtract {{{9}}} from both sides
{{{ 30 = 3x }}}
Divide both sides by {{{3}}}
{{{ x = 10 }}}
------------------------------
check the answer:
{{{ -39 = 3*( 10 - 3 ) - 6*10 }}}
{{{ -39 = 3*7 - 60 }}}
{{{ -39 = 21 - 60 }}}
{{{ -39 = -39 }}}
OK
