(x-12):11=39
(x-12) =39x11
(x-12) =429
x =429+12
x =441
<=> x - 12 = 39 * 11
<=> x - 12 = 429
=> x = 429 + 12
=> x = 441
Vậy x = 441
(x-12):11=39
x-12=39x11
x-12=429
x=429+12
x=441
(x-12):11=39
x-12=39 x 11
x-12=429
x=429+12
x=441
(x-12) \(\div\)11 = 39
x - 12 = 39 * 11
x - 12 = 429
x = 429 + 12
x = 441
