tìm x
a,(x-35)-120=0
b,124+(118-x)=217
c,156-(x+61)=82
tik mk na xong mk tik lại
( x - 35 ) - 120 = 0
124 + ( 118 - x ) = 217
156 - ( x + 61) = 32
tìm số tự nhiên biết x
giúp mk nha
mk cảm ơn các bạn rất nhiều
( x - 35 ) - 120 = 0
⇔ x - 35 = 120
⇔ x = 155
Vậy x = 155
124 + ( 118 - x ) = 217
⇔ 118 - x = 93
⇔ x = 25
Vậy x = 25
156 - ( x + 61) = 32
⇔ x + 61 = 124
⇔ x = 63
Vậy x = 63
(x-35)-120=0
(x-35)=0+120
(x-35)=120
x=120+35
x=155
vậy x=155
124+(118-x)=217
(118-x)=217-124
(118-x)=93
x=118-93
x=25
ậy x=25
156-(x+61)=32
(x+61)=156-32
(x+61)=124
x=124-61
x=63
vậy x=63
(x - 35) - 120 = 0
124 + (118 - x) =217
156 - (x + 61) = 82
a)(x-35)-120=0
x-35 =0+120
x-35 =120
x =120+35
x =155
b)124+(118-x)=217
118-x =217-124
118-x =93
x=118-93
x=25
c)156-(x+61)=82
x+61=156-82
x+61 =74
x =74-61
x =13
\(\left(x-35\right)-120=0\)
\(=>x-35=120\)
\(=>x=120+35\)
\(=>x=155\)
a) (x - 35) - 120 = 0
x - 35 = 120
x = 155
b) 124 + (118 - x) =217
118 - x = 217 - 124
118 - x = 93
x = 25
c) 156 - (x + 61) = 82
x + 61 = 156 - 82
x + 61 = 74
x = 13
1.Tìm x.
a) (x - 35) - 120 = 0 b) 124 + (118 - x) = 217 c) 156 - (x + 61) =82
x - 35 =..... 118 - x =..... x + 61 =.....
x-35 =.... 118 - x =..... x + 61 =.....
x =..... x = ..... x =.....
x =..... x = ..... x =.....
a/ \(\left(x-35\right)-120=0\)
\(\Leftrightarrow x-35=0+120\)
\(\Leftrightarrow x-35=120\)
\(\Leftrightarrow x=120+35\)
\(\Leftrightarrow x=155\)
Vậy ...
b/ \(124+\left(188-x\right)=217\)
\(\Leftrightarrow188-x=217-124\)
\(\Leftrightarrow188-x=93\)
\(\Leftrightarrow x=95\)
Vậy ...
b/ \(156-\left(x+61\right)=82\)
\(\Leftrightarrow x+61=74\)
\(\Leftrightarrow x=13\)
Vậy ..
a] [x - 35 ] - 120 = 0 b 156-[x+61] = 82 c] 124+ [118-x] = 217
a) (x-35) - 120 =0
b)124+(118-x)=217
c) 156-(x+61)=82
a (x-35)-120=0
=> x-35=120
=>x=155
b 124+(118-x)=217
=> 118-x=217-124
=> 118-x=93
=> x=25

a. ( x - 35) - 120 = 0
b. 124 + (118 - x) = 217
c. 156- (x + 61) = 82
a. ( x - 35) - 120 = 0
=> x-35=120
=> x=155
b. 124 + (118 - x) = 217

a)
\(\Rightarrow x-35=120\)
\(\Rightarrow x=155\)
Vậy x = 155
b)
\(\Rightarrow242-x=217\)
\(\Rightarrow x=25\)
Vậy x = 25
c)
\(\Rightarrow95-x=82\)
\(\Rightarrow x=13\)
Vậy x = 13
