9+x / 3x  =  5/6

If you look at it as a proportion, then you can "cross-multiply" it"

(9+x) · 6  =  3x · 5

54 + 6x  =  15x

Subtract 6x from each side:

54  =  9x

Divide each side by 9 :

6 = x

Simplify the expression: 7 - 7(5 + x) - 9x <br> Your answer
Gekata [30.6K]

Answer:

-16x-28

Step-by-step explanation:

Break it into little pieces; start with distributing the -7:

-7(5+x)

-35-7x

Now add the rest of the problem: 7-35-7x-9x

Combine like terms: 7-35               7x-9x

7-35=-28             7x-9x=-16x

Rearrange so the coefficient and variable are upfront, giving you:

-16x-28
