Another problem with my checking. The teacher says the answer is 280 but when I try to check it I never get the right one

(24-d)/16=19

• Math -

(24-d)/16=19

Multiply both sides by 16.

24-d = 304

-d = 304 - 24

d = -280

• Math -

work:
You multiply 16 by 16 and 19 by 16 then your left with 24-d=304 then you subtract 24 to the both sides, so when you subtract 24 from 304 yo get 280 and then b=280

• Math -

So is it 280 or -280?
