Question

What is the second step to solve the equation a = {c} / {d } - b. Solve for c

Answer 1

Let's begin by listing out the information given to us:

`a=(c)/(d )-b`

We are to solve for c

Step 1

Add b to both side. We have:

`\begin{gathered} a+b=(c)/(d)-b+b \\ \Rightarrow a+b=(c)/(d) \end{gathered}`

Step 2

Multiply by d, We have:

`\begin{gathered} d\cdot(a+b)=(c)/(d)\cdot d \\ \Rightarrow c=d(a+b) \end{gathered}`

Hence, the second step is to Multiply by d
