Question

Solve y = 4x + 8x for x​

Answer 1

Answer:

$\Huge \boxed{ x=\frac{y}{12} }$

$\rule[225]{225}{2}$

Step-by-step explanation:

$y=4x+8x$

Combining like terms.

$y=12x$

Dividing both sides by 12.

$\displaystyle \frac{y}{12} =x$

$\rule[225]{225}{2}$

Answer 2

Answer:

See below.

Step-by-step explanation:

So we have the equation:

$y=4x+8x$

And we want to solve it for x.

First, combine like terms on the right:

$y=12x$

Now, divide both sides by 12. The right will cancel:

$x=\frac{y}{12}$

And we're done :)
