Answer:

$x=4$

Step-by-step explanation:

So we have the equation:

$-(7-4x)=9$

Let's divide both sides by -1. This cancels out the negative on the left:

$7-4x=-9$

Subtract 7 from both sides. The left cancels:

$-4x=-16$

Divide both sides by -4. All the negatives will cancel:

$x=4$

And we're done!
