6 + 2n - 5 = 7n + 1 - 4n (combine like terms)
1 + 2n = 3n + 1 (subtract 1 from both sides)
2n = 3n (subtract 2n from both sides)
0 = n
n = 0 <===ANSWER
1 + 2n = 3n + 1 (subtract 1 from both sides)
2n = 3n (subtract 2n from both sides)
0 = n
n = 0 <===ANSWER

2n+1=3n+1
n=0
n=0

6 + 2n - 5 = 7n + 1 - 4n
2n - 7n + 4n = -6 + 1 + 5
-5n + 4n = -5 + 5
-n = 0
n = 0/-1
n = 0
2n - 7n + 4n = -6 + 1 + 5
-5n + 4n = -5 + 5
-n = 0
n = 0/-1
n = 0
