1-2n=-14+n can someone plz solve and explain this promblem

n=5

Step-by-step explanation:

1-2n=-14+n

Add 2n to each side to get all the "n" on one side

1-2n+2n =-14+n+2n

1 = -14 + 3n

Add 14 to each side to get all the constants on one side

1 +14 = -14 +14 +3n

15 =3n

Divide each side by 3 to isolate n

15/3 =3n/3

5 =n

b.-4 units

all you   do is count how many times you move
