25-10x=5
10x=25-5
10x=20
x=20:10
x=2
25 - 10x = 5
10x = 25 - x
10x = 20
x = 20 : 10
x = 2
10x=25-5
10x=20
x=20:10
x=2
tick mk nha bn
25 -10x = 5
10x = 25 - 5
10x = 20
x = 20 : 10
x = 2
25-10x=5
10x=25-5
10x=20
X=20:10
X=2
25 -10x = 5
10x = 25-5
10x =20
x=20:10
x=2
25-10x=5
=>10x=25-5
10x=20
x=20:2
x=2
25 - 10x = 5
10x = 25 - 5
10x = 20
x = 20 : 10
x = 2
bạn làm như sau: 25-10x=5
10x=25-5=20
x=20:10
x=2
25 - 10x = 5
10x= 25 -5 =20
x = 20 : 10 =2
