See the entire solution process below:

First, add the negative constants on the left side of the equation:

#-13 = 2x - 11#

Next, add #color(red)(11)# to each side of the equation to isolate the #x# term while keeping the equation balanced:

#-13 + color(red)(11) = 2x - 11 + color(red)(11)#

#-2 = 2x - 0#

#-2 = 2x#

Now, divide each side of the equation by #color(red)(2)# to solve for #x# while keeping the equation balanced:

#-2/color(red)(2) = (2x)/color(red)(2)#

#-1 = (color(red)(cancel(color(black)(2)))x)/cancel(color(red)(2))#

#-1 = x#

#x = -1#
