Basically the same way you solve an equation: isolate the variable on one side and the constants on the other:

#2x+10>8x-8#

#2x-8x>(-8-10)#

#-6x > (-18)#

Now, we need to divide by #-6#. This will change the signs on both sides, so we must reverse the direction of the inequality:

#(-6x)/-6 < (-18)/(-6)#

#x < 3#
