Answer:
320
Step-by-step explanation:
4*80=320
the number is - 1
let the number be n then 6 times the number is 6n and added to -4 is
- 4 + 6n = 10n ( equal to 10 times the number )
subtract 6n from both sides
- 4 = 4n ( divide both sides by 4 )
= n , hence n = - 1
positive = greater than 0.
Therefore we have the inequality:
|add 7 to both sides
