Đáp án :
( x – 73) – 111 = 54
x – 73 = 54 + 111
x – 73 = 165
x = 165 + 73
x = 238
1500:[(30 × x + 40): x] = 30
(30 × x + 40): x = 1500 : 30
30 × x + 40 : x = 50
30x : x + 40 : x = 50
30 + 40 : x = 50
40 : x = 50 – 30
40 : x = 20
x = 40 : 20
x = 2
237 – ( x – 11) = 58
x – 11 = 237 – 58
x – 11 = 179
x = 179 + 11
x = 190
