Tính nhẩm:
6 x 6 =
6 x 9 =
6 x 7 =
6 x 8 =
36 : 6=
54 : 6 =
42 : 6 =
48 : 6 =
Học sinh nhẩm và ghi:
6 x 6 = 36
6 x 9 = 54
6 x 7 = 42
6 x 8 = 48
36 : 6 = 6
54 : 6 = 9
42 : 6 = 7

tim x,biet
a)x-6=35:7+42:6
b)x-54:27=42-26:2
c)36:x+81:x=130:10
a. x -6 = 35 : 7 + 42 : 6
=> x - 6 = 5 + 7
=> x -6 = 12
=> x = 12 + 6
=> x = 18
Các câu sau tương tự, bạn học tốt nha! .-.
a)x-6=5+7
x-6=12
x=6.
b)x-2=42-13
x-2=29
x=29+2
x=31
c)(36+81):x=13
117:x=13
x=117:13
x=9.
a)x-6=35:7+42:6
x-6=5+7
x-6=12
x=12:6
x=2
Vậy x=2
42:X+36:X=6

Kết bạn với mk nha !
Tìm x:
a) 42 : x + 36 : x = 6 b) 90 : x – 48 : x = 3
6/7 : 18/42 x ( 1/2 + 36 x 1/8 )
