Answer:

I don't know if this is 100% right but i got no solution.

Step-by-step explanation:

2(n + 2) = 4n + 1 - 2n

I distributed the 2 evenly among the n and the 2

2n + 2 = 4n + 1 - 2n

Combine like terms

2n + 2 = 2n + 1

Subtract 1 from both sides

2n + 1 = 2n

This is how i got no solution, this equation cannot be equal.

Answer:no solution

Step-by-step explanation:

2(2 + n) = 4n + 1 + -2n

(2 * 2 + n * 2) = 4n + 1 + -2n

(4 + 2n) = 4n + 1 + -2n

Reorder the terms:

4 + 2n = 1 + 4n + -2n

Combine like terms: 4n + -2n = 2n

4 + 2n = 1 + 2n

Add '-2n' to each side of the equation.

4 + 2n + -2n = 1 + 2n + -2n

Combine like terms: 2n + -2n = 0

4 + 0 = 1 + 2n + -2n

4 = 1 + 2n + -2n

Combine like terms: 2n + -2n = 0

4 = 1 + 0

4 = 1

Solving

4 = 1

This equation is invalid, the left and right sides are not equal, therefore there is no solution.
