Find the value of d a = d² / -11d

The equation is given as:

$$a = \frac{d^2}{-11d}$$

Assuming $d \neq 0$, we can cancel one $d$ from the numerator and the denominator.

$$a = \frac{d \cdot d}{-11 \cdot d}$$ $$a = \frac{d}{-11}$$

To isolate $d$, multiply both sides of the equation by $-11$:

$$-11 \cdot a = -11 \cdot \frac{d}{-11}$$ $$-11a = d$$

Therefore, the value of $d$ in terms of $a$ is:

$$d = -11a$$
