Answer and Step-by-step explanation:


\Huge \boxed{n=-4}

Step 1: Simplify both sides of the equation:


n+3-4n=15


n+3+-4n=15


(n+-4n)+(3)=15 (Combine the like terms)


-3n+3=15

Step 2: Subtract 3 from both sides:


-3n+3-3=15-3


-3n=12

Step 3: Divide both sides by -3:


(-3n)/(-3) (12)/(-3)


n=-4

Answer:
n=-4

Answer:


\Huge \boxed{N=-4}

Explanation:

To solve this problem, first you have to isolate by the n from one side of the equation. Subtraction property of equality is subtracting both sides of an equation by the same number and it doesn't change the equation.

Given:

Solution:

First, combine like terms. (group like terms or switch sides.)


\displaystyle n-4n+3=15

Next, add numbers from left to right.


\displaystyle n-4n=-3n


\displaystyle -3n+3=15

Then, subtract 3 from both sides.


\displaystyle -3n+3-3=15-3

Solve.


\displaystyle 15-3=12


\displaystyle -3n=12

Now, divide by -3 from both sides.


\displaystyle (-3n)/(-3)=(12)/(-3)

Solve.


\displaystyle 12/-3=\boxed{-4}


\large\boxed{n=-4}

Therefore, the solution is n=-4, which is our answer.
