jeff said to his younger brother, mike "give me 8 of your video games, and then i'll have twice as many games as you have." Mike said, "No way! You give me 8 of your games, and then we'll have the same number of games." How many games did each boy have before any video games were swapped?

let jeff has video games before swapping =x=40

and after swapping 40+8=48

and mike has vedio games before swapping=y=32

and after swapping y=32+8=40

then from the question given

2(x + 8) =y..................................(1)

similarly y + 8 =x.........................(2)

now putting the value of x in equation (1)......

2(y+8+8)=y

2(y+16)=2y+32=y

2y-y=-32

y=32.....putting the value of y in equation 2 to calculate x...........

x=40
