#7-2n = n-14# #7+14 = n +2n# #21 = 3n# #21/3 = (3n)/3# #7 = n#
- You have the original equation
- Move similar variables onto one side and numbers on the other
- Add the variables/numbers on each side
- Divide by the number associated with n to isolate for
#n# - You are left with
#7# .#n = 7# - You can check
#7-2(7) = 7-14#

To solve this equation, first put the values with a variable on one side of the equals mark then the other numerical values on the other side. Be careful about the signs and solve the eq.as there is minus sign on both sides so they cancel out each other.

To solve the equation 7 - 2n = n - 14, first, add 2n to both sides to eliminate the term -2n on the left side:
7 - 2n + 2n = n - 14 + 2n 7 = 3n - 14
Next, add 14 to both sides to isolate the term 3n:
7 + 14 = 3n - 14 + 14 21 = 3n
Finally, divide both sides by 3 to solve for n:
21 / 3 = 3n / 3 7 = n
So, the solution to the equation is n = 7.
