Let x be the smaller no.
y be the larger no.
x+2=y---------1
x+y=46-------2
Put 1 into 2 ,
x+x+2=46
2x=44
x=22
Put x=22 into 1 ,
22+2=y
y=24
y be the larger no.
x+2=y---------1
x+y=46-------2
Put 1 into 2 ,
x+x+2=46
2x=44
x=22
Put x=22 into 1 ,
22+2=y
y=24

設其中一個數是X,則另一個數是X+2,得式,
X+X+2=46
2X+2=46
2X=44
X=22
己知X=22,那你只要加2,就可以求到另一個數為24.

記著要注意連續數這三個字.

不好意思,應是要加上"雙數"二字.
X+X+2=46
2X+2=46
2X=44
X=22

Let the first number be "X" and second be "Y"
Since the two even numbers are consecutive
Therefore,
Y= X +2
Therefore,
(X) + (X+2) = 46
2X +2 =46
2X= 44
X= 22
Y= 22+2= 24
Therefore,
the two numbers are 22 and 24.
