See a solution process below:

Explanation:

Multiply each side of the equation by #color(red)(18)# to solve for #x# while keeping the equation balanced:

#color(red)(18) xx -12 = color(red)(18) xx x/18#

#-216 = cancel(color(red)(18)) xx x/color(red)(cancel(color(black)(18)))#

#-216 = x#

#x = -216#
