Answer:

x=4

Step-by-step explanation:

-(7-4x)=9

-7+4x=9

4x=16

x=4

Answer:

[tex]x=4[/tex]

Step-by-step explanation:

So we have the equation:

[tex]-(7-4x)=9[/tex]

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

[tex]7-4x=-9[/tex]

Subtract 7 from both sides. The left cancels:

[tex]-4x=-16[/tex]

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

[tex]x=4[/tex]

And we're done!
