If it's 3 a.m
in Australia it is 4 p.m
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!
