Question 879582
Mac and his brother Ted collect coins. Mac's collection contains 8 more than twice as many as Ted's. If the total number of coins in the two collections is 74, how many coins are in each collection? 
If x represents the number of coins in Ted's collection, then which expression represents the number of coins in Mac's collection?

-----------------------------------------------------------------------------------------

To find the number of coins in Mac's collection, we should first find the number of coins in Ted's collection.

The number of coins in Ted's collection = x
The number if coins in Mac's collection = 2x+8

x+2x+8=74				1) Combine like terms
3x+8=74					2) Subtract
3x=66					3) Divide

x=22 <---- This is the number of coins in Ted's collection. Lets plug this number into 2x+8 to find how many coins Mac has.

2(22) +8 = 52

So Mac has 52 coins.
Hope this helped!
