a(n-3)=

Solution for a(n-3)= equation:

Simplifying
a(n + -3) = 0

Reorder the terms:
a(-3 + n) = 0
(-3 * a + n * a) = 0
(-3a + an) = 0

Solving
-3a + an = 0

Solving for variable 'a'.

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

Factor out the Greatest Common Factor (GCF), 'a'.

Subproblem 1
Set the factor 'a' equal to zero and attempt to solve:

Simplifying
a = 0

Solving
a = 0

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

Simplifying
a = 0
Subproblem 2
Set the factor '(-3 + n)' equal to zero and attempt to solve:

Simplifying
-3 + n = 0

Solving
-3 + n = 0

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

Add '3' to each side of the equation.
-3 + 3 + n = 0 + 3

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

Combine like terms: 0 + 3 = 3
n = 3

Add '-1n' to each side of the equation.
n + -1n = 3 + -1n

Combine like terms: n + -1n = 0
0 = 3 + -1n

Simplifying
0 = 3 + -1n
