28\sqrt{9}-16a=8\times 43
Ikkala tarafini 43 ga ko‘paytiring.
28\times 3-16a=8\times 43
9 ning kvadrat ildizini hisoblab, 3 natijaga ega bo‘ling.
84-16a=8\times 43
84 hosil qilish uchun 28 va 3 ni ko'paytirish.
84-16a=344
344 hosil qilish uchun 8 va 43 ni ko'paytirish.
-16a=344-84
Ikkala tarafdan 84 ni ayirish.
-16a=260
260 olish uchun 344 dan 84 ni ayirish.
a=\frac{260}{-16}
Ikki tarafini -16 ga bo‘ling.
a=-\frac{65}{4}
\frac{260}{-16} ulushini 4 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.
