Divide each term in An=4nn+3 by n.

Ann=4nn+3n

Cancel the common factor.

Ann=4nn+3n

Divide A by 1.

A=4nn+3n

A=4nn+3n

Multiply the numerator by the reciprocal of the denominator.

A=4nn+3⋅1n

Cancel the common factor of n.

Factor n out of 4n.

A=n⋅4n+3⋅1n

Cancel the common factor.

A=n⋅4n+3⋅1n

Rewrite the expression.

A=4n+3

A=4n+3

A=4n+3

Solve for A An=(4n)/(n+3)
