Joe has a collection of nickels and dimes that is worth $6.10. If the number of dimes was tripled and the number of nickels was decreased by 49, the value of the coins would be $14.05. How many nickels and dimes does he have? ----
let x be the number of dimes and y be the nickles x+y=6.10 3x+y-49=14.02
solve it to get the answer
solve it for me
lol, hashir.. solve.
awwwwww!!!!!!!!!!!!!!!11
>.> well show them how to solve it XD
hashir baita, aap kuch bhool rahay hain
x+y=6.10 3x+y-49=14.05
solve it urself honey girl!!!!!!!
yaad a gaya
baar baar na bhola karo!
i cannot get the second equation
3x=dimes tripled y-49=reduced by 49
then?
:P for the first equation subtract x or y, I'll solve for x since it's easier IMO. x = 6.10-y now plug in your new x into the second equation 3(6.10-y)+y-49 = 14.02 can you solve from here?
no
why not D:
tell me what you think you should do now
well you have to distribute 3. which means multiply 3 by everything in the ( ) so 3x6.10 and 3x-y so you get 18.30-3y+y-49=14.02
do you know how to combine like terms?
