Answer:
Step-by-step explanation:
how many coins: d + q = 200
value of the money .10d + .25q = 44
(ten cents for each dime and 25 cents for each quarter)
Now to solve by elimination:
1)multiply the first row by -10 so that the dimes will cancel out.
-.10d + -.10 q = 20 (don't do anything to second row)
.10d + .25q = 44
2) now add those up.
the dimes cancel out.
.15 q = 64
that does not divide evenly so there is something wrong with this problem.
