Question

Consider the equation representing a customer purchasing 3 boxes of cereal at $x each and 4 apples at Sy each at a grocery store for a total of $3x + 4y = 12 What is the equation when solved for y?

Answer 1

`y\text{ = }((12-3x))/(4)`

Here, we want to write the given equation in terms of y

Simply put, we want to make y the subject of the formula

We proceed as follows;

`\begin{gathered} \text{Given ;} \\ 3x\text{ + 4y = 12} \\ 4y\text{ = 12-3x (divide through by 4)} \\ y\text{ = }((12-3x))/(4) \\ \\ \end{gathered}`
