  1. a. X Quarters.

    b. 2x Dimes.
    (2x+22) Nickels.
    3(2x+22) Pennies.

    c. X + 2x +(2x+22) + 3(2x+22)=2134.
    X + 2x + 2x + 22 + 6x + 66 = 2134
    11x + 88 = 2134
    11x = 2046

    X = 186 Quarters.
    2x = 2*186 = 372 Dimes.
    2x+22 = 372 + 22 = 394 Nickels.
    3(2x+22) = 3 * 394 = 1182 Pennies.

  3. p = 2n
    n = d+11
    d = 3x
    n = 3x+11
    p = 2(3x+11) = 6x+22
    p+n+d+x = 4453
    6x+22 + 3x+11 + 3x + x = 4453
    13x + 33 = 4453
    13x = 4420
    x = 340
    So, we have
    340 quarters
    1020 dimes
    1031 nickels
    2062 pennies
    check: 340+1020+1031+2062 = 4453
