Answer:

Given the equation:
d = (LM)/(R_2+R_1) .....[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;


d(R_2 +R_1) = LM

Divide both sides by M we get;


L = (d(R_2+R_1))/(M)

or


L = (dR_2+dR_1)/(M)

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