\((x-17)+52=158\)
\(\Rightarrow x-17=158-52\)
\(\Rightarrow x-17=106\)
\(\Rightarrow x=106-17\)
\(\Rightarrow x=89\)
( x- 17 ) + 52 = 158
x - 17 = 158 - 52
x - 17 = 106
x = 106 + 7
x = 113
Vậy x = 113
( x : 23 + 45 ) : 67 = 8911
x : 23 + 45 = 8911 x 67
x : 23 + 45 = 597037
x : 23 = 597037 - 45
x : 23 = 596992
x = 596992 x 23
x = 13730816
Vậy x = 13730876
(x-17)+52=158
x - 17 = 158 - 52
x - 17 = 106
x= 106+17
x= 123
(x :23 + 45):67=8911
(x : 68 ) : 67 = 8911
x : 68 = 8911 * 67
x : 68 = 597037
x= 597037 x 68
x = 40598516
k mình nhé !!!
( x- 17 ) + 52 = 158
x - 17 = 158 - 52
x - 17 = 106
x = 106 + 17
x = 123
( x : 23 + 45 ) : 67 = 8911
x : 23 + 45 = 8911× 67
x : 23 + 45 = 597037
x : 23 = 5967037 - 45
x : 23 = 596992
x = 596992 × 23
x = 13 730 816
Vậy x = 13 730 816
