    Jason has an equal number of nickels and dimes. The total value of his nickels and dimes is $2.25. How many nickels does Jason have?

    Let the number of nickels be n
    Let the number of dimes be d

    We're given two equations:
    1. d = n
    2. 0.05n + 0.1d = 2.25
    Substitute equation (1) for d into equation (2):
    0.05n + 0.1n = 2.25

    Solve for n in the equation 0.05n + 0.1n = 2.25

    Step 1: Group the n terms on the left hand side:
    (0.05 + 0.1)n = 0.15n

    Step 2: Form modified equation
    0.15n = + 2.25

    Step 3: Divide each side of the equation by 0.15
    0.15n/0.15 = 2.25/0.15
    n = 15
