Answer:
Simplifying
3(n + -1) = 6
Reorder the terms:
3(-1 + n) = 6
(-1 * 3 + n * 3) = 6
(-3 + 3n) = 6
Solving
-3 + 3n = 6
Solving for variable 'n'.
Move all terms containing n to the left, all other terms to the right.
Add '3' to each side of the equation.
-3 + 3 + 3n = 6 + 3
Combine like terms: -3 + 3 = 0
0 + 3n = 6 + 3
3n = 6 + 3
Combine like terms: 6 + 3 = 9
3n = 9
Divide each side by '3'.
n = 3
Simplifying
n=3
