Waste of my time. The tip is to double check your answer
Thanks
Kelly, for others it's a short cut(low on time etc)
Agree, I did the problem in seconds.
@@enriqueiii9209 But did you do it in the correct way? Did you find the correct solution? When you solve an equation you can make a mistake and find a wrong answer. That's why a check is useful. And even then you are not sure about your answer:
5x+6=21. 5x= 15. x=10. Check: 5*10+6=15+6=21. So ok? 😊
(When you make the error in the second step of the solution there is a big chance that you make the same error in the first step of the check, because it seems that you think that 5*10 equals 15. And when you do that in the solution it is likely that you do that in the check as well.)
@@henkhu100 For this problem the answer is 3
5x+6=21
5x=15
x=3
