Answer 2

In an algebraic expression, letters can stand for variables. When we substitute a specific value for each variable, and then perform the substitution, it's called evaluating the expression.

Let's evaluate the expression 3x + 4x when x= -1

$\implies$3x+4x

$\implies$3(-1)+4(-1)

$\implies$-3+(-4)

$\implies$-3-4

$\implies$-7
