d(R2+R1)=LM
[d(R2+R1)]/M=L

Given the equation:        .....[1]

Cross multiply states that an equation of fractions when each of the side consists of a fraction with a single denominator by multiplying the numerator of each side by the denominator of the other side and equating these two products obtained.

Apply the cross multiply in [1], we get;

Divide both sides by M  we get;
