See a solution process below:

First, group and combine like terms on the left side of the equation:

#5x + 5x + 5 = 125#

#(5 + 5)x + 5 = 125#

#10x + 5 = 125#

Next, subtract #color(red)(5)# from each side of the equation to isolate the #x# term while keeping the equation balanced:

#10x + 5 - color(red)(5) = 125 - color(red)(5)#

#10x + 0 = 120#

#10x = 120#

Now, divide each side of the equation by #color(red)(10)# to solve for #x# while keeping the equation balanced:

#(10x)/color(red)(10) = 120/color(red)(10)#

#(color(red)(cancel(color(black)(10)))x)/cancel(color(red)(10)) = 12#

#x = 12#
