Question 579333
Transpose 4n to the left side of the equation and change its sign forming:

2n-4n-6=1 then transpose -6 to the right side and change its sign forming"

2n-4n=6+1 
--- -2n=7
divide both side of the equation by -2 to find n

n= -7/2 

to check: subtitute the given value to the given equation:

2(-7/2) -6 = 4(-7/2) + 1

-7-6= -14+1
-13=-13
