Question

Need help with this math problem

Answer 1

Answer:

A)

Step-by-step explanation:

Given expression:

$\boxed{\mathsf{c = 15 + am}}$

subtracting 15 from both sides, and combining like terms on the RHS

$\implies\mathsf{c - 15 = (15 - 15)+ am}$

Dividing both sides by a

$\implies\mathsf{ \frac{c - 15}{a} = am \times \frac{1}{a} }$

a On the RHS gets canceled for being present in both Numerator as well as denominator, and were left with the following equation:

$\implies\mathsf{ \frac{c - 15}{a} = m }$
