Question

Tìm x biết :

a/ (2367 - x) - 1017 = 205          b/ 5.(x + 35) = 515

Answer 1

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

Answer 2

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
