218 - x = 735 - 531
218 - x = 204
x = 218 - 204
x = 14
a ) 541 + ( 218 - x ) = 735
218 - x = 735 - 541
218 - x = 194
x = 218 - 194

Tìm x biết
a)541 + (218 - x) = 735
a)541 + (218 - x) = 735
(218 - x) = 735 - 541
(218 - x) = 194
x = 218 - 194
x = 24
A)541+(218-x)=735
541 + (218 - x) = 735
218 - x = 735 - 541 = 194
x = 218 - 194 = 24
541 + ( 218 -x) = 735
96 -3 X ( x + 1) = 42
5 X ( x +35) = 515
541 + ( 218 - x ) = 735
218 - x = 735 - 541
218 - x = 194
x = 218 - 194
x = 24
541 + (218 - x) = 735
=> 218 - x = 194
=> x = 218 - 194
x = 24
t i c k nhé!! 3463464457568797898746837316436545745
541 +(218-x)=735
541 +(218-x)=735
541+218-x=735
759-x=735
x=759-735=24
k mình nha bạn
541+(218-x)=735
218-x=735-541
218-x=194
x=218-194
x=24
541+(218-x)=735
541+(218-x)=735
759-x=735
x=759-735=24
\(541+ \left(218-x\right)=735\)
\(\Rightarrow218-x=735-541\)
\(\Rightarrow x=218-194\)
\(\Rightarrow x=24\)
