<h3>What is the expression?</h3>

An expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.

Suppose the number is x

$\frac{x}{80}+13=93$

Subtract 13 from both sides

$\frac{x}{80}+13-13=93-13$

$\frac{x}{80}=80$

Multiply both sides by 80

$\\\frac{80x}{80}=80\cdot \:80$

x=6400

Therefore the number is 6400.
