✔ 最佳答案
1a)Let the points that John get is xthen the point that Michael get is x+8
x/2+12=(x+8)
x/2=x-4
x=2x-8
x=8
The sorce of John is 8
and the sorce of Michael is 8+8=16
b)I think "scpre" should be "score"!
the total sorce of michael and john is 8+16=24

let x = John's score
then x+8 = Michael's score
x/2 + 12 = x+8
(a)
x/2 + 12 = x+8
12-8 = x - x/2
4=x/2
x=8
Michael's score = 16
(b)
x = 8 = John's score
Michael's score = 16
The total score of Michael and John is 16 + 8 = 24
then x+8 = Michael's score
x/2 + 12 = x+8
(a)
x/2 + 12 = x+8
12-8 = x - x/2
4=x/2
x=8
Michael's score = 16
(b)
x = 8 = John's score
Michael's score = 16
The total score of Michael and John is 16 + 8 = 24

let the score of michael be X, then john's equal to x-8
(X-8)/2= X-12
x-8= 2x-24
x=16
a/ micheal's score is 16
b/ john has 16-8=8 score, so total of both should be 16+8=24
(X-8)/2= X-12
x-8= 2x-24
x=16
a/ micheal's score is 16
b/ john has 16-8=8 score, so total of both should be 16+8=24

1)(a)16
(b)24
Because:
Let the score of John is n
so the score of Michael is 8+n.
n/2=8+n-12
n/2=n-4
n=2n-8
8+n=2n
8=n
P.S.:I don't mind you give us 5 score because I want help people.
(b)24
Because:
Let the score of John is n
so the score of Michael is 8+n.
n/2=8+n-12
n/2=n-4
n=2n-8
8+n=2n
8=n
P.S.:I don't mind you give us 5 score because I want help people.
