If I read your question right, then there are the same number of each type of coin.
Equation: 0.05X+%2B+0.10X+%2B+0.25X+=+4
Factor out an X on the left side
X%2A%280.05+%2B+0.10+%2B+0.25%29+=+4
Simplify
X%2A%280.4%29+=+4
Divide both sides by 0.4
highlight%28X+=+10%29
The are 10 of each type of coin
10 dimes, 10 nickels, 10 quarters
