See a solution process below:

First, multiply each side of the equation by #color(red)(2)# to eliminate the need for the parenthesis while keeping the equation balanced:

#color(red)(2) xx -3 = color(red)(2) xx 0.5(x + 4)#

#-6 = 1(x + 4)#

#-6 = x + 4#

Now, subtract #color(red)(4)# from each side of the equation to solve for #x# while keeping the equation balanced:

#-6 - color(red)(4) = x + 4 - color(red)(4)#

#-10 = x + 0#

#-10 = x#

#x = -10#
