8n-2n=12
subtract the n’s: 8n-2n= 6n
then divide both sides by 6: 6n/6= 12/6
the 6 with the n and the six that’s in the denominator cancel out then divide 12 by six so: n= 2

Yeah the one you chose is correct.
2/3 , 1
5. y=x+5 6. No solution.
To solve I used the graphing method. When graphing the first and second equation for number 5 I get the same line for both this is a dependent system meaning the solution would be the line itself y=x+5. 6. when simplified and graphed the graphs are y=x+5 and y=x+4. Both lines have the same slope and are perpendicular so they have no solution because they will never intersect.
