# What is the algebraic expression for: The sum of a number and two is three more than twice the same number?

May 19, 2018

($\Sigma$x+2) = 3 +2x

#### Explanation:

Let x represent the number
and indicates addition hence +2
thus $\Sigma$(x +2) is the sum of the number plus 2

this has to equal 3 + 2x (3 more then twice the same number)

hence the expression is then

$\Sigma$(x+2) = 3 +2x
