#x=-8#

Explanation:

The concept of this kind of equation is to combine like terms. So the first step is to add #30# to the eighteen on the other side. Then subtract the #3x# to the other #3x# on that side. You resultin #-6x=48#. Now what you have left is to divide the #-6# on both sides. You receive #x=-8#
