#x=-15#

Explanation:

What you'll want to do is get all the unknowns together, so subtract #2/5x# on both sides and do the same with #10# so all non-#x# items are on the other side.

At this point we have
#6-10=2/3x-2/5x#
To make this nice to look at, I'm going to multiply #2/3# by #5/5#
and #2/5# by #3/3#

Both numbers are equal to #1#and do not change the equation.
We then have
#6-10=10/15x-6/15x#
Now we can easily subtract both sides.

#-4=4/15x#

Lastly divide both sides by #4/15# to solve for #x#
The answer should be #x=-15#
