I just did this in math a couple weeks ago.  I forget how exactly to set up the equation.  It goes something like x+y+26=170.  Then, you subtract 26 from both sides to isolate x and y.  So then, the equation looks something like this x+y=144.  Then you divide 144 by 2, leaving you with 72.  You now add the 26 again, leaving you with the numbers 72 and 98.  72 + 98 is equal to 170.  Hope this helps.
