3 (n-1) = 6 what is the 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
