Question

11. Solve the equation for c:a + bc = 4d

Answer 1

Solve the equation for "c" means isolate "c".

So, follow the steps below to solve the question.

Step 01: subtract a from both sides of the equation.

`\begin{gathered} a+bc-a=4d-a \\ a-a+bc=4d-a \\ bc=4d-a \end{gathered}`

Step 02: Divide both sides by b.

`(bc)/(b)=(4d-a)/(b)`

Since b/b = 1:

`\begin{gathered} 1c=(4d-a)/(b) \\ c=(4d-a)/(b) \end{gathered}`

Answer: Option 2.

`c=(4d-a)/(b)`
