13x+5=15x-5
---------------------------
Subtract 15x from each side
13x+5-15x=15x-5-15x
-2x+5=-5
----------------------------------
Then, subtract 5 from each side
-2x+5-5=-5-5
-2x = -10
--------------------------------------------
Finally, divide each side by -2
-2x ÷ -2 = -10 ÷ -2
x = 5
----------------------------------------------------------------------------------------------------------------
x = 5 is your answer
