Question

what is 7n-5=11n-17 ?

Answer 1

what you want to do first is get n by it self

Answer 2

so add 5 to -17 and you will get 7n=11n-12

Answer 3

then you should subtract 11n from 7n and you will get -4n=-12

Answer 4

do you understand so far?

Answer 5

er..ok

Answer 6

anyways, you multiple both sides by -1/4 in order to get n=-3

Answer 7

The answer is 3. You have to move the 10 to right side of the equation which makes it positive so it is 11+10 on the right side. Then you divide both sides by 7 to isolate the n on the left side. 11+10 is 21 and 21 divided by 7 equals 3. :)
7n-10=11
7n=11+10
7n=21
7n/7=21/7
n=3

Answer 8

*n=3

Answer 9

yes
