Question

Solve the equation. -(7-4x)=9​

Answer 1

x=4

Explanation:

-(7-4x)=9

-7+4x=9

4x=16

x=4

Answer 2

`x=4`

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!
