#2x=(2/3x)-15# or #2x+15=(2/3x)#

We can start by assigning "The number" as #x#.
The question states that twice of #x#, #(2x)#, is 15 less than #2/3# of #x#.

That means that if we subtract 15 from #2/3x#, then #2x# should be equal to #2/3x-15#

Consequently, if we do that we are left with this:

#2x=(2/3)x-15#

#6x=2x-45#

#4x=-45#

#x=(-45)/4#
