Question 282220: translate the problem into a pair of linear equation in two variables.
problem= joe has a collection of nickles and dimes that is woeth $5.65, if the number of dimes was doubled & the number of nickles was increased by 20, then the value of the coins would be $10.15. how many dimes does he have? Answer by mananth(16946) (Show Source):
You can put this solution on YOUR website! Let the number of dimes be x
the number of nickels be y
10x+5y= 565 ( cents)
(10)*2x+(5)*(y+20) = 1015
20x+5y+100= 1015
-10x-100=565-1015
-10x=-350
x=35 which is number of dimes
y=43 number of nickels
