 Question 77829This question is from textbook : Sorry, but I have one more question on the substitution method. It is a+b=5000 and 0.08a=0.06b-20 THANKS ALOTThis question is from textbook Answer by uma(370)   (Show Source): You can put this solution on YOUR website! a+b = 5000 Adding -b to both the sides, a = 5000-b Substituting this in th second equation, 0.08(5000-b) = 0.06b - 20 ==> 400 - 0.08b = 0.06b - 20 ==> 400 + 20 = 0.06b + 0.08b [adding 0.08b + 20 to both the sides] ==> 420 = 0.14b ==> 420/0.14= 0.14b/0.14 ==> 3000 = b So a = 5000 - b = 5000-3000 = 2000 Thus a = 2000 and b = 3000 Good Luck
