b,[(10-x).2+]:3-2=3
tl nhớ kb vs mk na
a, 134: [x-3] = 35 + 160: 5
134 : [x-3] = 35 + 32
134 : [x-3] = 67
x - 3 = 134: 67
x-3 = 2
x = 2 + 3
x = 5
Bài b bạn ghi lại đề nha
a,134:(x-3)=35+160:5
=> 134:(x-3)=35+32
=> 134:(x-3)= 67
=> x - 3 = 134 : 67
=> x-3 = 2
=> x = 2 + 3 = 5
b,[(10-x).2]:3-2=3
=> [(10-x).2]:3 = 3+2
=> [(10-x).2]:3 = 5
=> (10 -x) . 2 = 5.3
=> (10 - x).2 = 15
=> 10-x = 15: 2
=> 10 - x =7,5
=> x = 10 - 7,5 = 2,5
a,134:(x-3)=35+160:5
134:(x-3)=35+32
134:(x-3)=67
(x-3)=134:67
x-3 =2
x =2+3
x =5
b,[(10-x).2+]:3-2=3
[(10-x).2+]:3=3+2
[(10-x).2+]:3=5
(10-x).2+=5.3
(10-x).2+=15
(10-x) =15:2
10-x=7,4
x=10-7,4
x=2,6
134 - (y-3) = 35 + 160 : 5
\(134-\left(y-3\right)=35+160:5\)
\(\Rightarrow134-\left(y-3\right)=35+32\)
\(\Rightarrow134-\left(y-3\right)=67\)
\(\Rightarrow y-3=134-67\)
\(\Rightarrow y-3=67\)
\(\Rightarrow y=67+3\)
\(\Rightarrow y=70\)
`134-(y-3)=35+160:5`
`=>134-(y-3)=35+32`
`=>y-3=134-(35+32)`
`=>y-3=134-67`
`=>y-3=67`
`=>y=70`
Vậy `x\in{70}`
Tìm x
\(134\div\left(x-3\right)=35+160\div5\)
\(134\div\left(x-3\right)=35+160\div5\)
\(134\div\left(x-3\right)=35+32\)
\(134\div\left(x-3\right)=67\)
\(x-3=134\div67\)
\(x-3=2\)
\(x=3+2\)
\(x=5\)
hok tốt
134 : (x - 3) = 35 + 160 : 5

Dãy số có 2 chữ số chia hết cho 3 là:[12,15,....,99]
Khoảng cách của từng số hạng là 3
Số số hạng là: (99-12):3+1=30(số)
Vậy có 30 số có 2 chữ số chia hết cho 3
