Answer:

#x=-3#

Explanation:

On the left, we can distribute the #5#, and the right we can distribute the #4#. After doing this, we get

#45-5x=4x+72#

Next, let's subtract #45# from both sides to get

#-5x=4x+27#

Next, we can subtract #4x# from both sides to get

#-9x=27#

Our last step would be to divide both sides by #-9#. We get

#x=-3#

Hope this helps!
