a) \(y-6:2-\left(48-24.2:6-3\right)=0.\)
\(\Rightarrow y-3-\left(48-8-3\right)=0\)
\(\Rightarrow y-3-37=0\)
\(\Rightarrow y=0+37+3=40\)
Vậy y = 40
b) \(\left(7.13+8.13\right):\left(9\frac{2}{3}-y\right)=39\)
\(\Rightarrow195:\left(\frac{29}{3}-y\right)=39\)
\(\Rightarrow\frac{29}{3}-y=195:39=5\)
\(\Rightarrow y=\frac{29}{3}-5=\frac{14}{3}\)
Vậy y=\(\frac{14}{3}\)
a) y - 6 : 2 - ( 48 - 24 x 2 : 6 - 3 ) = 0
y - 6 : 2 - ( 48 - 48 : 6 - 3 ) = 0
y - 6 : 2 - ( 48 - 8 - 3 ) = 0
y - 6 : 2 - 37 = 0
y - 3 = 0 + 37
y - 3 = 37
y = 37 + 3
y = 40
b) ( 7 x 13 + 8 x 13 ) : ( \(9\frac{2}{3}\) - y ) = 39
( 15 x 13 ) : ( \(9\frac{2}{3}\) - y ) = 39
195 : ( \(9\frac{2}{3}\) - y ) = 39
\(9\frac{2}{3}\) - y = 195 : 39
\(9\frac{2}{3}-y=5\)
\(y=9\frac{2}{3}-5\)
\(y=\frac{14}{3}\)
a) y - 6 chia 2 - ( 48 - 24 x 2 chia 6 - 3 ) = 0
=> y - 6 chia 2 - ( 48 - 48 chia 6 - 3 ) = 0
=> y - 6 chia 2 - ( 48 - 8 -3 ) = 0
= > y - 6 chia 2 - 37 = 0
=> y - 6 chia 2 = 0 + 37
=> y - 6 chia 2 = 37
=> y -6 = 37 chia 2
=> y - 6 = 37 / 2
=> y = 37 / 2 + 6
=> y = 49 / 2
Vậy y = 49 / 2
b) ( 7 x 13 + 8 x 13 ) chia ( 92 /3-y ) = 39
=> ( 91 + 104 ) chia ( 92/3 - y ) =39
=> 195 chia ( 92 /3 - y ) = 39
=> 92/3 - y = 7605
=> y = 7605 + 92/3
=> y = 22907 /3
Vậy y = 22907 / 3
80 - 4 . 52 + 3 .23=80 - 4 . 25 + 3 . 8=80 - 100 +24=-20+24=4
25 . 124 - 24 . 25 +212=24 .(124 - 25)+212=24 . 99 +212=2376 +212=2588
35 . 48 + 65 . 68 + 20 . 35=35 . (48 +20)+65 . 68=35 . 68 +65 . 68=68 . (35 + 65)=68 . 100=6800

câu 3,câu 6,câu 7 mk ko làm đc vì ko biết cách viết dấu móc vuông với dấu móc kép nha bạn.:) ^_^

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) \(20-\left[7\left(x-3\right)+4\right]=2\Rightarrow7\left(x-3\right)+4=20-2=18\)

cau sau cung tuong tu nhu zay
tự làm nha
nhớ k đó
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
\(x-68:69-\left(48-24.2:6-3\right)=0\)
\(x-\frac{68}{69}-\left(48-8-3\right)=0\)
\(x-\frac{68}{69}-37=0\)
\(x-\frac{68}{69}=37\)
\(x=\frac{2621}{69}\)
x - 68 : 69 - (48 - 24 * 2 : 6 - 3) = 0
x - 68 : 19 - 48 + 24 x 2 : 6 + 3 = 0
x - 68 : 19 - 48 + 24 x 2: 6 = 0 + 3
x - 68 : 19 - 48 + 24 x 2: 6 = 3
x - 68 : 19 - 48 + 24 x 2 = 3 x 6
x - 68 : 19 - 48 + 24 x 2 = 18
x - 68 : 19 - 48 + 24 = 18 : 2
x - 68 : 19 - 48 + 24 = 9
x - 68 : 19 - 48 = 9 - 24
x - 68 : 19 - 48 = -15
x - 68 : 19 = ( - 15 ) + 48
x - 68 : 19 = 33
