#### Answer

Translation to algebraic expression (not simplified):
$5x-2x$
Simplified form:
$3x$

#### Work Step by Step

Let
$x$ = the unknown number
The product of five and a number: $5x$
Twice the number: $2x$
The difference between the product of five and a number and twice the number: $5x - 2x$
Simplifying gives:
$=x(5-2)
\\=x(3)
\\=3x$
