Question

4x+3y= 12 She this literal equation for y. How do I do this?

Answer 1

Given the equation:

$4x+3y=12$

Solve for y means to make y alone on the left side

so, subtract 4x from both sides

so,

$\begin{gathered} -4x+4x+3y=12-4x \\ 3y=12-4x \end{gathered}$

Now, divide both sides by 3

So,

$\begin{gathered} \frac{3y}{3}=\frac{12-4x}{3} \\ \\ y=-\frac{4}{3}x+4 \end{gathered}$
