Sal keeps quarters, nickels, and dimes in his change jar. He has a total of 52 coins. He has 3 more quarters than dimes and five fewer nickels than dimes. How many dimes does Sal have?

The number of dimes is x.
The number of nickles is x - 5.
The number of quarters is x + 3
Therefore x + (x - 5) + (x + 3) = 52
3x - 2 = 52
3x = 54
x = 18
So Sal has 18 dimes, 21 (x + 3) quarters, and 13 (x - 5) nickles for a total of 52 (18 + 21 + 13) coins.

Quarters + Dimes + Nickles = 52
Quarters = Dimes + 3 (D+3)
Dimes = (D)
Nickles = Dimes - 5 (D-5)
Restate the formula
(D+3)+(D)+(D-5)=52
3D-2=52
3D=54
D=18
Q=21
N=13
Total Dimes = 18
Total Quarters = 21
Total Nickles = 13
Total Coins = 52

Quarters = x+3
Nickels = x - 5
Dimes = x
total coins = 52 coins
equation:
X + 3 + X - 5 + X = 52
combine like terms & simplifies to:
3X - 2 = 52
Add 2 to both sides...
simplifies to
3X = 54
Divide by coefficient of X ...(3)
X = 18 dimes
