t(n)=-6+3(n-1)

Solution for t(n)=-6+3(n-1) equation:

Simplifying
t(n) = -6 + 3(n + -1)

Multiply t * n
nt = -6 + 3(n + -1)

Reorder the terms:
nt = -6 + 3(-1 + n)
nt = -6 + (-1 * 3 + n * 3)
nt = -6 + (-3 + 3n)

Combine like terms: -6 + -3 = -9
nt = -9 + 3n

Solving
nt = -9 + 3n

Solving for variable 'n'.

Move all terms containing n to the left, all other terms to the right.

Add '-3n' to each side of the equation.
-3n + nt = -9 + 3n + -3n

Combine like terms: 3n + -3n = 0
-3n + nt = -9 + 0
-3n + nt = -9

Reorder the terms:
9 + -3n + nt = -9 + 9

Combine like terms: -9 + 9 = 0
9 + -3n + nt = 0
