Answer:
Number of 5 dollar bills = 23
Number of 10 dollar bills = 13
Step-by-step explanation:
Let number of 5 dollar bills be x
and the number of 10 dollar bills be y
Total $245, means we can write:
5x + 10y = 245
Ten more 5 dollar bills than 10 dollar bills, means:
x - 10 = y
Now we substitute 2nd equation in first and solve for x:
Also,
y = x - 10
y = 23 - 10 = 13
So there are 23 5-dollar bills and 13 10-dollar bills

Answer:
x=5
Step-by-step explanation:
Step 1: you want to have x alone on one side so I will subtract one x from both sides (to remove the 1 x on the right side). Now we're left with 3x=15.
Step 2: Divide both sides by 3 (to remove the 3 in front of 3x). Now we have x=5.
