Coincident lines are lines that are the same.
In the beginning of both equations we have '4x' and '8x'.
Note that 8 / 4 = 2.
Multiply the rest of the numbers in the first equation by 2.
5y * 2 = 10y
8 * 2 = 16
So our 2nd line will be:
8x + 10y = 16
He has 11 quarters, 9 dimes, and 55 nickels.
11x.25=2.75
9x.1=.9
55x.05=2.75
2.75+2.75+.9=6.4
