2n-6=n+4 -4 on both
2n-10 = n /2 on both
N-10 = 1/2n
n=20 |

2n-6=n+4
add 6 to both sides
2n = n + 10
take away n from both sides
n = 10 |

sure alright so first we gotta take 6 away from 2n
so what you gotta do is get a chair, tie a noose from your ceiling, put your head in the noose and kick the chair so you snap your neck and die

ALL THESE GUYS ARE TROLLS!
1. 2n - 6 = n + 4
2. -n = -n
3. n - 6 = 4
4. +6 = + 6
5. n = 10 |

2n-6=n+4
add 6 to 2n-6
that makes 2n
however, we also have to add 6 to n+4 to keep it balanced (to not change the formula)
this means 2n=n+10
we can then take out n from the equation making
n=10
ta dah |

| you do the inverse operation for the number so you can cancel it out and get your variables on one side |

How did you get 6 for 4 to become 10 if you say the 6 on the left how did you move itt
you have to get the variable 'n' by itself so you move n on the right to the left (right to left eithe way, you'll get the same)
then you add the 6 because 6 is a negative so you add 6 to 4 to get 10 |
