Answer:
5x + 10y = 125
Step-by-step explanation:
Let :
Number of nickel = x
Number of dime = y
Nickel = 5 cent
Dime = 10 cent

Total value should be converted to cent since both dime and nickel are both in cent
= $1.25 * 100 = 125 cents
Therefore,
5x + 10y = 125 cents
we are given that
both sides are equal
so, their length must be equal


now, we can find other side


now, we can set them equal


now, we can take square both sides

now, we can solve for p
