B, 38 . x – x . 12 – x . 16 = 40
x ( 38 – 12 – 16 ) = 40
x . 10 = 40
=> x = 40 : 10 = 4
C, 165-(35 : x + 3) .19=13
(35 : x + 3) .19 = 165 – 13
(35 : x + 3) .19 = 152
35 : x + 3 = 152 : 19
35 : x + 3 = 8
35 : x = 8 – 3
35 : x = 5
x = 7
D, x+5.2-(32+16.3:16-15) = 0
x + 10 – 32 – 16 . 3 : 16 – 15 = 0
x – 22 – 48 : 16 – 15 = 0
x – 22 – 3 – 15 = 0
x = 0 + 15 + 3 + 22
x = 40
B, 38.x-x.12-x.16=40
x.(38-12-16) =40
x.10 =40
x =40÷10
x =4
Vậy x =4
C, 165-(35:x+3) .19=13
(35:x+3) .19=165-13
(35:x+3) .19=152
(35:x+3) =152÷19
35:x+3 =8
35:x =8-3
35:x =5
x =35÷5
x =7
Vậy x =7
D, x+5.2-(32+16.3:16-15) = 0
x +10-32-16.3:16-15 = 0
x – 22 – 48 : 16 – 15 = 0
x – 22 – 3 – 15 = 0
x = 0 + 15 + 3 + 22
x = 40
Vậy x = 40
