suy ra: (x +35) =515 :5
suy ra; x +35=103
suy ra: x=103-35
suy ra: Vậy x=68
đúng nha!!!!!! 100% lun!!!!!!!! !!!!!!!!!!
5(x+35) = 515
x + 35 = 515 : 5
x + 35 = 103
x = 103 - 35
x = 68
5(x + 35) = 515
x + 35 = 515:5
x + 35 = 103
x = 103 – 35
x = 68
Vậy x = 68
\(5\left(x+35\right)=515\)
\(x+35=515:5\)
\(x+35=103\)
\(x=103-35\)
\(x=68\)
a/ (2367 - x) - 1017 = 205
2367-x=205+1017
2367-x=1222
x=2367-1222
x=1145
b/ 5.(x + 35) = 515
x+35=515:5
x+35=103
x=103-35
x=68
a) 2367 - x = 205 + 1017
2367 - x = 1222
x = 2367 - 1222
x = 1145
b) 5 . ( x + 35 ) = 515
x + 35 = 515 : 5
x + 35 = 103
x = 103 - 35
x = 68
25.3-x=104
75-x=104
x=75-104
x=-29
3(5x-15)-52=68
3(5x-15)=68+52
3(5x-15)=120
5x-15=120:3
5x-15=40
5x=40+15
5x=55
x=55:5
x=11
5(x+35)=515
x+35=515:5
x+35=103
x=103-35
x=68
515 : (x + 35) = 5
x + 35 = 515 : 5
x + 35 = 103
x = 103 - 35
x = 68
515 : (x + 35) = 5
x + 35 = 515 : 5
x + 35 = 103
x = 103 - 35
x = 68
Vậy x = 68
trả lời tiếp nè
c) 3.(x+1)=96-42
3.(x+1)=54
x+1=54:3
x+1=18
x=18-1
x=17
tick nha
218 - x = 735-541
218 - x = 194
x = 218 - 194
x = 24
Đúng 10000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000
b)5.(x + 35) = 515
(x + 35)= 515:5
(x + 35) = 103
x = 103-35
x = 68
