Here is the equation: x+(x+20) = 120 Since you can't combine anything yet, its x+x+20=120 You need to get x by itself Minus 20 from both sides Its x+x=100 now Combine the x's which is now 2x Now divide 100 by 2 which is 50 x=50 --------------- Lets check: 50+(50+20)=120 Now combine the numbers in the parentheses Its now 50+70=120 50+70=120 and 70-50=20 As you can see, he ran 50 minutes the first day and 70 minutes the second day
