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} (3y)/(3)=(12-4x)/(3) \\ \\ y=-(4)/(3)x+4 \end{gathered}`
