Step-by-step explanation:

Answer:-

[tex]\tt{y = 4x+8x}[/tex]

First, we need to add up the x.

We know that 4+8 = 12, so

[tex]\tt{4x+8x=12x}[/tex]

Now, equating it to y,

[tex]\tt{y = 12x}[/tex]

Now, if I multiply [tex]\tt{\dfrac{1}{12}}[/tex] on both sides,

I get,

[tex]\tt{\dfrac{y}{12}= \dfrac{\cancel{12}x}{\cancel{12}}}[/tex]

Now, as 12 got cancelled , I got the final answer as

[tex]\boxed{\tt{x =\dfrac{y}{12}}}[/tex]

Hope it helps :)
