Tìm số tự nhiên \(x\), biết :
a) \(541+\left(218-x\right)=735\)
b) \(5\left(x+35\right)=515\)
c) \(96-3\left(x+1\right)=42\)
d) \(12x-33=3^2.3^3\)
a) 541 + (218 - x) = 735
\(\Rightarrow\) 218 - x = 735 - 541
\(\Rightarrow\) 218 - x = 194.
\(\Rightarrow\) x = 218 - 194
\(\Rightarrow\) x = 24
b) 5(x + 35) = 515
\(\Rightarrow\) x + 35 = 515 : 5 = 103.
\(\Rightarrow\) x = 103 - 35
\(\Rightarrow\) x =68.
c) 96 - 3(x + 1) = 42
\(\Rightarrow\) 3(x + 1) = 96 - 42 = 54
\(\Rightarrow\) x + 1 = 54 : 3
\(\Rightarrow\) x = 18 - 1
\(\Rightarrow\) x = 17
d) 12x - 33 = 32 . 33
\(\Rightarrow\) 12x - 33 = 243
\(\Rightarrow\)12x = 243 + 33
\(\Rightarrow\) 12x = 276.
\(\Rightarrow\) x = 23.
a) 541 + (218 - x) = 735
Suy ra 218 - x = 735 - 541 hay 218 - x = 194.
Do đó x = 218 - 194. Vậy x = 24.
b) 5(x + 35) = 515 suy ra x + 35 = 515 : 5 = 103.
Do đó x = 103 - 35 =68.
c) Từ 96 - 3(x + 1) = 42 suy ra 3(x + 1) = 96 - 42 = 54. Do đó x + 1 = 54 : 3 = 18. Vậy x = 18 - 1 hay x = 17.
d) Từ 12x - 33 = 32 . 33 hay 12x - 33 = 243 suy ra 12x = 243 + 33 hay 12x = 276. Vậy x = 23.
