Respuesta :

[tex]y\text{ = }\frac{(12-3x)}{4}[/tex]

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;

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