Answer 3

Let's break down the steps you provided:

1. $478 + 12$ is a simple addition, which equals $490$.
2. You set up an equation $490 ÷ x = 70$.

To solve for $x$, we can isolate it by multiplying both sides of the equation by $x$:

$x \times \frac{490}{x} = 70 \times x$

This simplifies to:

$490 = 70x$

Now, we can solve for $x$ by dividing both sides by 70:

$x = \frac{490}{70} = 7$

So, $x = 7$.
