X = 15
Inverse operations would be + 5 to the -5 which cancels that out, & adding 5 to the 15 which gives you 15
First you have to order the set of values:
1, 1, 1, 2, 3, 3, 5, 7, 8, 8, 9
Now you just have to look for the middle value, which is 3.
Therefore your final answer is 3 :)

He saved $3.30 in all.
Step-by-step explanation:
Let,
Number of nickels = x
Number of dimes = y
According to given statement;
Jeff saved 33 more nickels than dimes.
x = y+33 Eqn 1
He had 4 times as many nickels as dimes.
x = 4y Eqn 2
Putting value of x from Eqn 2 in Eqn 1
Dividing both sides by 3
Putting y=11 in Eqn 2
Therefore,
Total coins = 44 nickels + 11 dimes
We know that;
1 nickel = 5 cents
1 dime = 10 cents
Total coins worth = 44*5 + 11*10 = 220+110 = 330 cents
Dividing by 100 to convert into dollars
He saved $3.30 in all.
