first simplify with distribuation 6x-5=5x-15+x
add like terms 6x-5=6x-15
then well you sure this is the correct question
then add 5 to both sides 6x=6x-10
then are you sure this is correct
then sub 6x from both sides so 0 = -10
which it doesn't so this would be false
if you have to find x then well I think you got the wrong question.
