50 coins total
v of the P10.00 coins
50-v of the P5.00 coins

10v%2B5%2850-v%29=335

Let x = number of P10.00 coins
50-x = number of P5.00 coins
Equation:
10x + 5(50-x) = 335
10x + 250 - 5x = 335
Combine like terms:
10x - 5x = 335 -250
5x = 85
x = 17
Answer:
There are 17 P10.00 coins out of 50 coins.
Solved.
