ur answer. 12 = \\frac{4}{3}u

$ur answer. 12 = \\frac{4}{3}u$

ur answer.
12 = \frac{4}{3}u

To eliminate the fraction, multiply both sides of the equation $12 = \frac{4}{3}u$ by 3. This gives $12\times3 = 4u$.
$36 = 4u$

To solve for $u$, divide both sides of the equation $36 = 4u$ by 4.
$u=\frac{36}{4}$
$u = 9$

$u = 9$
