The value of K is about −0.532.

Step-by-step explanation:

The given equation is

2.5+0.5-(1.6-(3.2+2.1\div K))=0.65

It can be rewritten as

2.5+0.5-(1.6-(3.2+\frac{2.1}{K}))=0.65

On simplify we get

3-(1.6-3.2-\frac{2.1}{K})=0.65

3-(-1.6-\frac{2.1}{K})=0.65

3+1.6+\frac{2.1}{K}=0.65

4.6+\frac{2.1}{K}=0.65

Subtract 4.6 from both sides.

\frac{2.1}{K}=0.65-4.6

2.1=-3.95K

Divide both sides by -3.95.

\frac{2.1}{-3.95}=K

−0.53164556=K

K\approx −0.532

Therefore, the value of K is about −0.532.
