Hi, I have three systems of equations word problems. Can you help me? #1: The sum of three numbers is 32. The largest if 4 times the smallest. The sum of the two smaller numbers is 8 less than the largest. What are the numbers? I have tried to model this one. I got: _ + _ +_ = 32 Largest = 4S Sum of the two smaller #S = L-8 Then I don't know what to do from there and got lost. #2: Dat is 10 years older than David. 38 years ago, he was twice as old as him. How old is David now? This was one of my equations that I tried to come up with: Y = D+10 Y = 2D + 38 Yeah, it doesn't really add up and so I don't really know what do with it. #3: Tiffany has 34 animals. She has 3 times as many birds as cats. She has 4 times as many cats as dogs. How many of each does she have? For this one I got: 34 = B+C+D Birds = 3C Cats = 4D Then I got put into a loop of plugging in values, so I need help building the equations wit
