6x-2=2x-7
+2 +2
6x= 2x-5
-2x -2x
4x = -5
/4 /4
X=-5/4
27+19 can be re-written as : 19+27
Now we can add them.

Answer:
8 nickels and 9 dimes
Step-by-step explanation:
If all were dimes, the value would be $1.70. It is $0.40 less than that. Changing a dime for a nickel reduces the value by $0.05, so there must have been $0.40/$0.05 = 8 such changes.
There are 8 nickels and 9 dimes.
