Simplifying
5n + 3 = 2 (n + 2) + 3n
Reorder the terms:
3 + 5n = 2 (n + 2) + 3n
Reorder the terms:
3 + 5n = 2 (2 + n) + 3n
3 + 5n = (2 * 2 + n * 2) + 3n
3 + 5n = (4 + 2n) + 3n
Combine like terms: 2n + 3n = 5n
3 + 5n = 4 + 5n
Add '-5n' to each side of the equation.
3 + 5n + - 5n = 4 + 5n + - 5n
Combine like terms: 5n + - 5n = 0
3 + 0 = 4 + 5n + - 5n
3 = 4 + 5n + - 5n
Combine like terms: 5n + - 5n = 0
3 = 4 + 0
3 = 4
Solving
3 = 4
The left and right sides are not equal, therefore there is no solution.
