Question

N+3-4n=15
Need to see the steps I solve it but can't brake down the steps. Please help.

Answer 1

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 2

`\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.
