**smith Descomb**, Wednesday, March 30, 2011 at 9:47pmSolution: Make 2 equations out of the problem

ex. X for jeans y for sweater

175= 25x=20y the price of the all the jeans + the price of all the sweater= 175 dollars

8=x-y the number of jeans and sweater = the number of item

get X by itself and use substitution

8-y=x now substitute it in the first problem

175=(8-Y)=20y

175=200-25Y+20Y now combine like term

175=200-5Y get y by itself first - 200 on both side the divide -5 on both to get y by itself and your answer is the number of sweater

Now plug the 5 in the second equation 8=y+x now plug in 5 for Y

8=5+x -5 on both side to find the number of jeans

Hope u get this !!!!
