If a-2y = bx-3x = y, then is it true that a = bx-3x = 3y ? If not, then how can I find x and y?

#x=a/(3(b-3))# and #y=a/3#

Explanation:

If #a-2y=bx-3x=y#, then we cannot say #a=bx-3x=3y#.

We can solve it the following way

#a-2y=y# and this implies that #a=3y# or #y=a/3#

Hence #bx-3x=a/3#

or #(b-3)x=a/3# or #x=a/(3(b-3))#
