a, 541 + (218 - x) = 735
218 - x = 735 - 541
218 - x = 194
x = 218 - 194
x = 24
Vậy x = 24
b, 5(x + 35) = 515
x + 35 = 515 : 5
x + 35 = 103
x = 103 - 35
x = 68
Vậy x = 68
c, 96 - 3(x + 1) = 42
3(x + 1) = 96 - 42
3(x + 1) = 54
x + 1 = 54 : 3
x + 1 = 18
x = 18 - 1 = 17
Vậy x = 17
d, 12x - 33 = 32 . 33
12x - 33 = 35
12x - 33 = 243
12x = 243 + 33
12x = 276
x = 276 : 12
x = 23
Vậy x = 23
Ủng hộ mk nha !!! ^_^
