124 + ( 118 - x ) = 217
tìm x
tìm x 124+(118-x)-125
đề đúng bn ạ tại bn ko bt lam thôi
coi minh làm nè
124+118-x-125
x=124+118-125
x=242-125
x=117
Tìm số tự nhiên x, biết: 124 + (118 – x ) = 217
124 + (118 – x ) = 217
118 – x = 217 – 124
118 – x = 93
x = 118 – 93
x = 25.
bài tìm x 124+(118-X)-215
bai nay phai co ket ua moi lam duoc chu
Tìm x:
124 + ( 118 - x ) = 217
124+(118-x)=217
(118-x)=217-124
(118-x)=93
x=118-93
x=25
Kết quả:25
124+(118-x)=217
118-x=217-124
118-x=93
-x=93-118
-x = -25
x=25
124+(118-x)=217
(118-x)=217-124
118-x = 93
-x = 118-93
-x = 25
x =-25
124 - ( 118 - x ) = 217 315 + ( 146 - x ) = 401 575 - ( 6x + 70 ) = 445 315 + ( 125 - x ) = 435
\(124 - (118 - x) = 217\)
\(118-x=124-217\)
\(118-x=-93\)
\(x=118-\left(-93\right)\)
\(x=211\)
\(---\)
\(315+(146-x)=401\)
\(146-x=401-315\)
\(146-x=86\)
\(x=146-86\)
\(x=60\)
\(---\)
\(575-(6x+70)=445\)
\(6x+70=575-445\)
\(6x+70=130\)
\(6x=130-70\)
\(6x=60\)
\(x=60:6\)
\(x=10\)
\(---\)
\(315+(125-x)=435\)
\(125-x=435-315\)
\(125-x=120\)
\(x=125-120\)
\(x=5\)

124 - ( 118 - x ) = 217
118 - x =124-217
118 - x =-93
x=118-(-93)
x= 211
315 + ( 146 - x ) = 401 \
146 - x=401-315
146 - x= 83
x= 146-83
x=63
575 - ( 6x + 70 ) = 445
6x + 70=575-445
6x + 70=130
6x=130-70
6x =60
x=60:6
x=10
315 + ( 125 - x ) = 435
125 - x=435-315
124-x=120
x=124-120
x=4
124+[118-x] = 217
124 + ( 118 - x ) = 217
118 - x = 217 - 124
118 - x = 93
x = 118 - 93
x = 25
x = 25 nha bn iu k cho milk nha
124+(118-x)=217
=> 124 + 118 - x = 217
=> 242 - x = 217
=> x = 25
118-x= 217-124
118-x= 93
x= 118-93
x= 25
\(124+\left(118-x\right)=217\)
\(118-x=217-124\)
\(118-x=93\)
\(x=118-93\)
\(x=25\)
124+(118-x)=217
(118-x)=217-124
118-x=93
x=118-93
x=25
Vậy x=25
124+(118-x)=217
118-x = 217 - 124
118-x = 93
x = 118 - 93
x = 25
Vậy ...
124 + (118 -x) =217
118 - x = 217 - 124
118 - x = 93
x = 118 - 93
x = 25
vậy x = 25
124+[118-x]=217
