(x+35)+(x+124)=549
(-136) - x biết rằng
a) x = (-35)
b) x = 145
c) x = (- 124) - 36
a: (-136)-(-35)=-136+35=-101
b: -136-145=-281
c: (-136)+124+36=160-136=24
a) x = - 35
⇒ - 136 - x = - 136 - (- 35) = -136 + 35 = -101
b) x = 145
⇒ - 136 - x = - 136 - 145 = -281
c) x = - 124 - 36 = -160
⇒ - 136 - x = - 136 - (- 160) = -136 + 160 = 24

Làm nhanh hộ em với ạ
123 x 35 + 124 x 65
Làm nhanh giúp mik nhà MN
\(123\times35+124\times65\)
\(=123\times35+\left(123+1\right)\times65\)
\(=123\times35+123\times65+65\)
\(=123\times\left(35+65\right)+65\)
\(=123\times100+65\)
\(=12300+65\)
\(=12365\)
123 x 35 + 124 x 65
= 123 x 35 + 123 x 65 + 65
= 123 x (35 + 65) + 65
= 123 x 100 + 65
= 12300 + 65
= 12365

Làm hộ e với ạ
123 x 35 + 124 x 65

( x - 35 ) - 112 = 0
124 + ( 118 - x ) = 27
156- ( x + 61 ) = 82
a)
( x - 35 ) - 112 = 0
=> x - 35 = 0 + 112 = 112
=> x = 112 + 35 = 147
b)
124 + ( 118 - x ) = 27
=> 124 + 118 - x = 27
=> 242 - x = 27
=> x = 242 - 27 = 215
c)
156 - ( x + 61 ) = 82
=> 156 - x - 61 = 82
=> 95 - x = 82
=> x = 95 - 82 = 13
a) \(\left(x-35\right)-112=0\)
\(\Rightarrow x-35=112\)
\(\Rightarrow x=147\)
b) \(124+\left(118-x\right)=27\)
\(\Rightarrow118-x=-97\)
\(\Rightarrow x=215\)
c) \(156-\left(x+61\right)=82\)
\(\Rightarrow x+61=74\)
\(\Rightarrow x=135\)

câu c tự giải nhé ( **** cho mình nha)
a) (x-35)-120=0
=>x-35=120
=>x=85
(x-35)-120=0 x-35 =0+120 x-35 =120 x =120+35 x =155
a) (x-35)-120=0
b)156-(x+61)=82
c)124+(188-x)=217
a, (x - 35)-120=0
x-35=120+0
x-35=120
x=120+35
x=155
b,156-(x+61)=82
x+61=156-82
x+61=74
x=74-61
x=13
c,124+(188-x)=217
188-x=217-124
188-x=93
x=188-93
x=95
a) ( x - 35 ) - 120 = 0
x - 35 = 0 + 120
x - 35 = 120
x = 120 + 35
x = 155
b) 156 - ( x + 61 ) = 82
x + 61 = 156- 82
x + 61 = 74
x = 74 - 61
x = 5
c) 124 + ( 188 - x ) = 217
188 - x = 217 - 124
188 - x = 93
x = 188 - 93
x = 95
K MK NHA BẠN, MK CHẮC ĐÚNG LUN ĐÓ NHA, THANK BẠN NHÌU
a) (x-35)-120=0 b)156-(x+61)=82 c)124+(188-x)=217
=>X-35=0+120=120 =>x+61=156-82=74 =>188-x=217-124=93
=>X=120+35=155 =>x=74-61=13 =>x=188-93=95 ai thấy dung k nha :)))
