( x - 3 ) - 120 = 0
<=> x - 3 = 120
<=> x = 120 + 3
<=> x = 123
8x - 3 = 0
<=> 8x = 3
<=> x = 3 : 8
<=> x = 3/8

2 phan kia ban tu lam nhe
xong nho an dung cho minh
1/ a, \(50-\left[30-\left(6-2\right)^2\right]\)
\(=50-\left[30-3^2\right]\)
\(=50-30+9\)
\(=20+9=29\)
2/ a, \(124+\left(118-x\right)=217\)
\(\Leftrightarrow118-x=3\)
\(\Leftrightarrow x=115\)
Vậy ...
b/ \(814-\left(x-305\right)=712\)
\(\Leftrightarrow x-305=102\)
\(\Leftrightarrow x=407\)
Vậy ...
c/ \(x-32:16=48\)
\(\Leftrightarrow x-2=48\)
\(\Leftrightarrow x=50\)
Vậy ...
d/ \(\left(x-32\right):16=48\)
\(\Leftrightarrow x-32=768\)
\(\Leftrightarrow x=800\)
Vậy .
Trả lời
a)134+(118-x)=277
118-x =277-134
118-x =143
x =118-143
x =-25
b)x-32:16=48
=>x-2 =48
=>x =48+2
=>x =50
Rất vui khi được giúp bạn !
\(a,134+\left(118-x\right)=277\)
\(134+118-x=277\)
\(252-x=277\)
\(-x=25\)
\(x=-25\)
\(b,x-32:16=48\)
\(x-2=48\)
\(x=50\)
a) x-32:16=48
x-2=48
x=48+2
x=50
Vậy x \(\varepsilon\) {50}
b)(x-32):16=48
x-32=48.16
x-32=768
x=768+32
x=800
Vậy x \(\varepsilon\) {800}
c)Thiếu đầu mối.
d)815-(x-306)=713
x-306=815-713
x-306=102
x=102+306
x=408
Vậy x \(\varepsilon\) {408}.
Tích đúng nếu bạn thấy nó đúng chuẩn nhé.

Dung thi k cho minh nha!!!
(x-32):16=48
=> x-32=48.16
=> x-32=768
=> x=768+32
=> x=800
x-32:16=48
=> x-2=48
=> x=48+2
=> x=50
( x - 32 ) : 16 = 48
x - 32 = 48 . 16
x - 32 = 768
x = 768 + 32= 800
x - 32 : 16= 48
x - 2 = 48
x = 48 + 2= 50
a) 460 + 85.4 = ( x + 200 ) : 4

b) => x = 2595
c) => x = 50
d) => x = 40
a)460 +85 . 4 = (x+200) :4 b)x:15+42=15+25.8
suy ra : 460+340=(x+200):4 suy ra: x:15+42=15+200
suy ra: 800= (x+200):4 suy ra : x:15+42=215
suy ra : 800.4=x+200 suy ra: x:15=215-42
suy ra : 3200=x+200 suy ra : x:15=173
suy ra: x= 3200-200 suy ra : x=173.15
suy ra : x=3000 vậy x =3000 suy ra: x=2595 vậy x = 2595
c) x-32:16=48 d)x-6:2-(48-24.2:6-3)=0
suy ra :x-2=48 suy ra : x-6:2-(48-48:6-3)=0
suy ra :x=48+2 suy ra : x-6:2-(48-8-3)=0
suy ra : x=50 suy ra : x-6:2-(40-3)=0
vậy x=50 suy ra : x-6:2 - 37=0
