5n + 4= (n + 1) -2n
4=(n + 1) - 2n - 5n
4= n + 1 - 2n-5n
4-1=n-2n-5n
3=-6n
3\-6 =-6n/-6
-1/2=n

Answer:

Explanation:

Simplifying

5n + 4 = 7(n + 1) + -2n

Reorder the terms:

4 + 5n = 7(n + 1) + -2n

Reorder the terms:

4 + 5n = 7(1 + n) + -2n

4 + 5n = (1 * 7 + n * 7) + -2n

4 + 5n = (7 + 7n) + -2n

Combine like terms: 7n + -2n = 5n

4 + 5n = 7 + 5n

Add '-5n' to each side of the equation.

4 + 5n + -5n = 7 + 5n + -5n

Combine like terms: 5n + -5n = 0

4 + 0 = 7 + 5n + -5n

4 = 7 + 5n + -5n

Combine like terms: 5n + -5n = 0

4 = 7 + 0

4 = 7

Solving

4 = 7
