#s = 6#

To solve equality you must perform the necessary operation to isolate the variable, in this case #s# while always keeping the equation balanced.

First, add 10 to each side of the equation:

#4s - 10 +10 = 8 + s + 10#

#4s - 0 = 18 + s#

#4s = 18 + s#

Next, subtract #s# from each side of the equation:

#4s - s = 18 + s - s#

#(4 - 1)s = 18 + 0#

#3s = 18#

Finally divide each side of the equation by #3#:

#(3s)/3 = 18/3#

#1s = 6#

#s = 6#
