nhớ kick cho mình nha
Tìm x biết:
a, 12*(x+41)=624
(x+41)=624:12
(x+41)=52
x+41=52
x=52-41
x=11.
b, 420:(3*x-6)=7
(3*x-6)=420:7
(3*x-6)=60
3*x-6=60
3*x=60+6
3*x=66
x=66:3
x=33
k cho mình nhé, kết bạn không........................
mình nhầm nha 66:3=22 đó sửa lại hộ mình
\(12\left(x+41\right)=624\)
<=> \(x+41=52\)
<=> \(x=11\)
\(420:\left(3x-6\right)=7\)
<=> \(3x-6=60\)
<=> \(3x=66\)
<=> \(x=22\)
học tốt
tìm x biết:
12. (x +41)=624
x + 41 =624 : 12
x +41 =52
x =52-41
x =11
420:(3. x-6)=7
3.x-6 =420:7
3.x-6 =60
3.x-6 =60:+6
3. x =66
x =66:3
x =22
tìm x biết:
12. ( x + 41 ) = 624
x + 41 = 624 : 12
x + 41 = 52
x = 52 - 41
x = 11
Vậy x = 11
420 : ( 3 . x - 6) = 7
3. x - 6 = 420 : 7
3 . x - 6 = 60
3 . x = 60 + 6
3 . x = 66
x = 66 : 3
x = 22
Vậy x = 22
\(12.\left(x+41\right)=624\)
\(\Rightarrow x+41=52\)
\(\Rightarrow x=11\)
Vậy\(x=11\)
\(420:\left(3.x-6\right)=7\)
\(\Rightarrow3x-6=60\)
\(\Rightarrow3x=66\)
\(\Rightarrow x=22\)
Vậy\(x=22\)
