Solution for 3n-2=15+3n equation:
Simplifying
3n + -2 = 15 + 3n
Reorder the terms:
-2 + 3n = 15 + 3n
Add '-3n' to each side of the equation.
-2 + 3n + -3n = 15 + 3n + -3n
Combine like terms: 3n + -3n = 0
-2 + 0 = 15 + 3n + -3n
-2 = 15 + 3n + -3n
Combine like terms: 3n + -3n = 0
-2 = 15 + 0
-2 = 15
Solving
-2 = 15
Couldn't find a variable to solve for.
This equation is invalid, the left and right sides are not equal, therefore there is no solution.
