7(x+5)=-28\\7x+(7*5)=-28\\7x+35=-28\\7x+35-35=-28-35\\7x=-63\\(7x)/(7)=(-63)/(7)\\x=-9\\\\6x=-54

Answer:

-54

Step-by-step explanation:

First we need to use the distributive property on 7(x+5), so do 7×x + 7×5. Simplify that and you get 7x+35.

Subtract 35 from both sides and you get 7x= -63. Divide both sides by 7 and you get x= -9.

Now we can substitute -9 for x, so do 6×-9 and you get -54.

Hope this helps :)
