The answer will be
#x = 3#

Explanation:

First, we will take the #-1# to the RHS. As it is negative, sending to RHS will make it positive. Therefore

#3x = 8 + 1#
#3x = 9#

Now we will send #3# to the RHS. As #3# is the multiple of #x#, sending it to RHS will make it a divisor.

#x = 9/3#

Hence

#x = 3#
