$$L_1=q_1\lambda_1/2n\,\!$$

$$L_2=q_2\lambda_2/2n\,\!$$

which gives us:

Eq.1 $$c=\nu_1\lambda_1\,\!$$

Eq.2 $$c=\nu_2\lambda_2\,\!$$

Now we say

Eq.3 $$\Delta\nu=\nu_1-\nu_2\,\!$$

then we can use $$2\cdot Eq.1 - 2\cdot Eq.2$$

which then gives us

$$c=2\nu_1\lambda_1-\nu_2\lambda_2\,\!$$

which, upon substitution of Eq.3, we get

$$c=\nu_1(2\lambda_1-\lambda_2)+\Delta\nu\lambda_2\,\!$$
