x + 5 . 2 - ( 32 + 16 . 3 : 6 - 15 ) = 0
x + 10 - ( 32 + 8 - 15 ) = 0
x + 10 - 25 = 0
x - 15 = 0
x = 15
x - 6 : 2 - ( 48 - 24 ) : 2 : 6 - 3 = 0
x - 3 - 24 : 2 : 6 - 3 = 0
x - 3 - 2 = 0
x - 5 = 0
x = 5
x + 5 . 2- (32+48:6-15)=0
x+5.2-(32+8-15)=0
x+5.2-25=0
x+10=0+25=25
x=25-10
x=15
cau sau cung tuong tu nhu zay
tự làm nha
nhớ k đó
x-6:2(48-24.2:6-3)=0
\(\Rightarrow\)x-6:2(48-48:6-3)=0
\(\Rightarrow\)x-6:2(48-8-3)=0
\(\Rightarrow\)x-6:2.37=0
\(\Rightarrow\)x-3.37=0
\(\Rightarrow\)x-111=0
\(\Rightarrow\)x=111
Vậy x=111
x-6:2-(48-24):2:6-3=0
=> x-3-24:2:6-3=0
=> x-3-2-3=0
=> x=0+3+2+3
=> x=8
x-6:2-(48-24):2:6-3=0
=> x-3-24:2:6-3=0
=> x-3-2-3=0
=> x= 0+3+2+3
=> x=8
x-6:2-[48-24]:2:6-3=0
=>x-3-24:2:6=0+3
=>x-3-12:6=3
=>x-3-2=3
=>x-3=3+2
=>x-3=5
=>x=5+3
=>x=8
x-6-(48-24x2:6-3)=100
x-6-(48-8-3)=100
x-6-37=100
x-6=137
x=137+6=143
Vậy x=143
20-[7x(X-3)+4]=2
7x(X-3)+4=20-2
7x(X-3)+4=18
7x(X-3)=14
X-3=14:7
X-3=7
X=7+3=10
Vậy X=10
[(6.X-39):3].28=5628
(6.X-39):3=5628:28
(6.X-39):3=201
6.X-39=201.3=603
6.X=603+39
6.X=642
X=642:6=107
Vậy x=107
1) \(x-6-\left(48-24.2:6-3\right)=100\Rightarrow x-6-\left(48-8-3\right)=100\)
\(\Rightarrow x-6-37=100\Rightarrow x=100+37+6=143\)
2) \(20-\left[7\left(x-3\right)+4\right]=2\Rightarrow7\left(x-3\right)+4=20-2=18\)
\(\Rightarrow7\left(x-3\right)=18-4=14\Rightarrow x-3=14:7=2\Rightarrow x=2+3=5\)
3) \(\left[\left(6x-39\right):3\right].28=5628\Rightarrow\left(6x-39\right):3=5628:28=201\)
\(\Rightarrow6x-39=201.3=603\Rightarrow6x=603+39=642\Rightarrow x=642:6=107\)
x - 6 : 2 - ( 48 - 24 ) : 2 : 6 = 3
=> x - 3 - 24 : 2 : 6 = 3
=> x - 3 - 12 : 6 = 3
=> x - 3 - 2 = 3
=> x = 3 + 2 + 3
=> x = 8
vậy_
x - 6 : 2 - 24 : 2 : 6 = 3
x - 3 - 12 : 6 = 3
x - 3 - 2 = 3
x - 3 =5
x = 8
