-7
OpenStudy (anonymous):
okay. let me write this down.
OpenStudy (anonymous):
yes. so what the next step? Thank you.
OpenStudy (anonymous):
\[\sqrt{5n-7}=-4\]we can't simplify the inside of the square root any further so the next step is squaring both sides.
OpenStudy (anonymous):
This will get rid of the square root

OpenStudy (anonymous):
@moha_10 It's not about you. We can care less if you know how to solve we want to the asker to be able to solve it.

we just transfer the numbers to another side
OpenStudy (anonymous):
like \[5n-7=16\]
OpenStudy (anonymous):
great @kitsune0724 Now we have to add 7 to both sides.
This will get rid of the -7 from the left hand side.
OpenStudy (anonymous):
What do we get now?
OpenStudy (anonymous):
23

\[5n=23\]great now we want to get rid of that 5. The way to do this is by dividing both sides by 5
OpenStudy (anonymous):
What do we get now?
OpenStudy (anonymous):
4.6?
OpenStudy (anonymous):
\[n=4.6\]Yes good job!
OpenStudy (anonymous):
thank you so much!
