First set up the equation.
x + 3x = 648
Then solve for x.
4x = 648
Divide both sides by 4.
x = 162. So the answer for the system would be $162 and the price for the games would be $486. Add the two up to check your work and you will get $648. Hope this helped!

Answer:
2.625 pounds are left or 2 5/8
Step-by-step explanation:
So if your going to be subtracting a fraction from a whole number your going to have to consider the fact that the whole number can be divided up into that fraction.
So in this equation we are subtracting 2 3/8 from 5, we are going to take one from 5 and make it into a fraction so we can subtract:
5 = 4 8/8
Now we subtract 2 3/8 from 4 8/8
4 8/8 - 2 3/8 = 2 5/8
so there's your answer 2 5/8 pounds are left over, but if you wanted the answer in a decimal you would divide 5 by 8:
5/8 = 0.625
you then add 0.625 to 2:
2 + 0.625 = 2.625
And that is also your answer: 2.625 lbs. were left over.
