#x# =4.444 or #x# = #40/9#

Start by bringing all like terms on one side:

#2/5##x#- #5/8##x# = -16 +15

Here, notice that the signs flip on going to the other side.

So you get:

-#9/40##x# = -1

Here -#9/40# is multiplied to #x# so it'll go to the other side by division. This will cancel the negative sign of #-1#.

So you get:

#x# = 4.4444

or

#x# = #40/9#
