put this solution on YOUR website!just distribute the the negative sign through out the parenthesese. like so
x-15x+6=104
Then put the two x's together like so
-14x+6=104
Then do 104 minus 6 which equals 98 so now the problem looks like
-14x=98
then divide 98 by -14 and get an answer of
-7 which then means x=-7
