Use calculator 14.15 didvided by 5 is 2.83
3x+50=6x-10
subtract 3x
50=3x-10
add 10
60=3x
divide by 3
20=x
6!+7!+8!=(n)(6!)
calculate the individual values first:
6!=720
7!=5040
8!=40320
plug them into the equation:
720+5040+40320=n720
solve for n
5760+40320=n720
46080=n720
divide both sides by 720 to isolate n
46080/720=n720/720
64=n
