Tìm x thuộc N biết x - 6 : 2 - ( 48 - 24 : 2 : 6 - 3) = 0.
Tìm y biết:
y – 6 : 2 – ( 48 – 24 x 2 : 6 – 3) = 0
Tìm y biết:
y – 6 : 2 – ( 48 – 24 x 2 : 6 – 3) = 0
Tìm y biết:
a) y – 6 : 2 – ( 48 – 24 x 2 : 6 – 3) = 0
Tìm x biết
x - 6 : 2 - ( 48 - 24 ) : 2 : 6 + 3 = 0
x - 6:2-(48-24):2:6+3 = 0
x- 3 - 24 :2:6+3=0
x-3-2+3 = 0
x-3-2 = 0+3
x-3-2=3
x-3=3+2
x-3=5
x=5+3
x=8
x - 6 : 2 - ( 48 - 24 ) : 2 : 6 + 3 = 0
x - 6 : 2 - 24 : 2 : 6 + 3 = 0
x - 3 - 12 : 6 + 3 = 0
x - 3 - 2 + 3 = 0
x - 3 - 2 =0-3
x - 3 - 2 =-3
x - 3=-3+2
x - 3=-1
x=-1+3
x=2
Tìm x, biết:
x - (48 - 24 x 2 : 6 - 3 ) = 0
x - ( 48 - 24 x 2 : 6 - 3 ) = 0
x = 48 - 24 x 2 : 6 - 3
x = 48 - 48 : 6 - 3
x = 48 - 8 - 3
x = 40 - 3
x = 37
Vậy x = 37
Tham khảo nha !!!
x-(48-48:6-3)=0
x-(48-8-3)=0
x-37=0
x=0+37
x=37
Ta có : x - (48 - 24 x 2 : 6 - 3 ) = 0
=> x = 48 - 24 x 2 : 6 - 3
=> x = 48 - 8 -3
=> x = 40-3
=> x = 37
Vậy ...............
Tìm x, biết:
a, 390 – (x – 7) = 169:13
b, (x – 140) : 7 = 3 3 - 2 3 . 3
c, x – 6 : 2 – (48 – 24) : 2 :6 – 3 = 0
d, x + 5.2 – (32+16.3:6 – 15) = 0
a, x = 384
b, x = 161
c, x = 8
d, x = 15
Tìm x, biết:
a) 390 - ( x - 7 ) = 169 : 13
b) x - 6 : 2 - ( 48 - 24 ) : 2 : 6 - 3 = 0
c) ( x - 140 ) : 7 = 3 3 - 2 3 . 3
d) x + 5 . 2 - ( 32 + 16 . 3 : 6 - 15 ) = 0
Tìm y biết:
a. y – 6 : 2 – ( 48 – 24 x 2 : 6 – 3) = 0
b. (7 x 13 + 8 x 13) : ( 9 2 3 – y) = 39
a. Tính đúng y = 40
b. Tính đúng y = 4 2 3
Tìm x, biết:
a, 390- ( x - 7) = 169:13
b, x-6:2-(48-24):2:6-3=0
a)390-(x-7)=169:13
<=>390-(x-7)=13
<=>x-7=390-13
<=>x-7=377
<=>x=377+7
<=>x=384
b)x-6:2-(48-24):2:6-3=0
<=>x-3-24:2:6-3=0
<=>x-6-12:6=0
<=>x-6-2=0
<=>x-8=0
<=>x=8
a) 390 - ( x - 7 ) = 169 : 13
390 - ( x - 7 ) = 13
x - 7 = 390 - 13
x - 7 = 377
x = 377 + 7
x = 384
b) x - 6 : 2 - ( 48 - 24 ) : 2 : 6 - 3 = 0
x - 3 - ( 48 - 24 ) : 2 : 6 = 0 + 3 = 3
x - 3 - ( 48 - 24 ) : 2 = 3 x 6 = 18
x - 3 - ( 48 - 24 ) = 18 x 2
x - 3 - 24 = 36
x - 3 = 36 + 24
x - 3 = 60
x = 60 + 3
x = 63
Jang Ha Na làm sai mà cũng đc ****
