the second one first you want to subtract 14 from both sides so you get 5(2x-10)/2=5. next you want to divide both sides by 5 because it works out very nicely and you get (2x-10)/2=1. next you can take out the 2 on the left because 2x-10 can also be written as 2(x-5) so you would get x-5=1. and lastly you add 5 to both sides so x=6
