It is 2x + 5. The value of this expression will depend on the value of x: each different value of x will give a different value for the expression.
Find the value of the expression.
equation is an expression equated to a value..what you have written is an expression. when equated to a value or any other expression makes it an equation.

X2 (5)2 = 25 (- 5)2 = 25 An identity, almost, as any number put into this expression will yield the same value.
The vertex of this parabola is at 5 5 When the x-value is 6 the y-value is -1. The coefficient of the squared expression in the parabola's equation is -6.

When you have an algebraic expression with variables in it, you need to know the the value of each variable. The value of the expression is found by replacing the variables with their values and simplifying. For example, evaluate 2xy-3x if x=5 and y=-1. 2xy-3x = 2*5*(-1) -3*5 = -10-15 = -25.
