200-18:(372:3:x-1)-28=166 tìm x
200-18:(372:3:x-1) = 166 + 28
200-18:(372:3:x-1) = 194
18:(372:3:x-1) = 200 – 194
18:(372:3:x-1) = 6
372:3:x-1 = 18 : 6
372:3:x-1 = 3
124 : x = 3+1
124 : x = 4
X = 124 : 4
X = 31
x : 18 = 24
x = 24 x 18
x = 432
ủng hộ cho mình lên 200 nhaaaaaaaaaaa
200 - 18 : ( 372 : 3 : x x 1 ) - 28 = 166
200 - 18 : ( 372 : 3 : x - 1 ) = 166 + 28
200 - 18 : ( 372 : 3 : x - 1 ) = 194
18 : ( 372 : 3 : x - 1 ) = 200 - 194
18 : ( 372 : 3 : x - 1 ) = 6
372 : 3 : x - 1 = 18 : 6
372 : 3 : x - 1 = 3
124 : x = 3 + 1
124 : x = 4
x = 124 : 4
x = 31
X : 18 = 24
=> X = 24 x 18
=> X = 432
Vậy X = 432
Kích mình nha
