Question 813734: For the following question we are asked to writea sytem of equations and solve:
"Twice a smaller number is inreased by the larger is 45. Four times the larger decreasedvby 5times the smaller is 24. Find the numbers."
My system of equations was: 2S+L=45 and 4L-5S=24
After working it out my answer was S=12 and L=21 but after comparing answers with my friends they all got a different answer, however I cannot remember what the answer was.... What do you think I did wrong? Found 2 solutions by richwmiller, mananth:Answer by richwmiller(17219) (Show Source):
You can put this solution on YOUR website! You did nothing wrong. You have the right answers for the problem as you presented it.
test them
they work.
The others have wrong answers.
2S+L=45 and 4L-5S=24
plug S & L to check
2*12+21=45
so you are right
4*21-5*12=24
setting up equation is fine.
unless you have copied the problem wrong
