#x=3/2#

Explanation:

First, rearrange the equation so that the variables are on one side and constant is on the other side.

#-7x=-15/2 - 3#

Now work on one side at a time, so first solve for #-15/2 -3#

#-15/2 - 6/2#

That would give #-21/2#

Therefore we now have, #-7x=-21/2#

Now divide both sides by -7

#-7x/-7=-21/2/-7# The -7 would cancel out and give a positive one.

#x=-21/2/-7#

Therefore, #x=21/14# which can be simplified to #x=3/2#
