1/4k = 3 (-1/4k + 3)

Arada [10]

Answer:

For the expression $\frac{1}{4} k = 3 (-\frac{1}{4}k +3)$

k = 9 is the required solution.

Step-by-step explanation:

Here, the given expression is $\frac{1}{4} k = 3 (-\frac{1}{4}k +3)$

Solving the above expression for k, we get:

$\frac{1}{4} k = 3 (-\frac{1}{4}k +3) \implies \frac{k}{4} = (\frac{-3}{4}k) + 9$

or, $\frac{k}{4} + (\frac{3}{4}k) = 9 \implies \frac{k + 3k}{4} = 9$

or, $\frac{4k}{4} = 9 \implies k =9$

or, k = 9

Hence for the expression $\frac{1}{4} k = 3 (-\frac{1}{4}k +3)$

k = 9 is the required solution.
