x + 123 + x = 383
x + x + 123 = 383
2x + 123 = 383
2x = 383 - 123
2x = 460
x = 460 : 2
x = 230
x + 123 + x = 383
2x + 123 = 383
2x = 383 - 123
2x = 260
x = 260 : 2
x = 130
x + 123 + x = 383
x . 2 + 123 = 383
x . 2 = 383-123
x . 2 = 270
x = 270 : 2
x = 135
x+123+x=383
xx2=383-123
xx2=260
x=260:2
x=130
k mk nha
\(x+123+x=383\)
\(2x+123=383\)
\(2x=383-123\)
\(2x=260\)
\(x=130\)
k mk nha
thank you very much
x + 123 + x = 383
x + x + 123 = 383
x + x =383 - 123
x + x = 260
x = 260 : 2
x = 130
tk mk nha ,mk nhanh nhat do
x + 123 + x = 383
2x = 383 - 123
2x = 260
x = 260 : 2
x = 130
k cho tui
x + 123 + x = 383
x + x = 383 - 123
x + x = 260
x x 2 = 260
x = 260 : 2
x = 130
t toi tui t lai, hua do
x + 123 + x = 383
x + x = 383 - 123
x + x = 460
→ 2x = 460
x = 460 : 2
x = 230
TK nhé
thanks nhiều
