Bài này lm lâu lm đó nhớ k mik nha
541 + ( 218 - x ) = 735
=> 541 + 218 - x = 735
=> x = 541 + 218 - 735
=> x = 24
96 - 3 . ( x + 1 ) = 42
=> 3 . ( x + 1 ) = 96 - 42
=> 3 . ( x + 1 ) = 54
=> x + 1 = 54 : 3
=> x + 1 = 18
=> x = 18 - 1
=> x = 17
541+(218-x)=735
218-x = 735-541
218-x = 194
x=218-194=24
96-3.(x+1)=42
3.(x+1)=96-42
3.(x+1)=54
x+1=54:3=18
x=18-1=17
