Find the value of x in the equation x plus 5 equals x plus 45?
There is no numerical value for 'x' that can make this a true statement.
What is FOR NO VALUE in math?
If an expression is true "for no value" of x, it means that there is no value you can substitute for x to make it true. For example, x=x+1 is true for no value of x, because x is always strictly less than x+1.
What value of x makes the sentence true x+8=17?
18
What are identities trigonometry?
Identities are "equations" that are always true. For example, the equation sin(x) = cos(x) is true for x = pi/4 + kpi radians where k is any integer [ = 45 + 180k degrees], but for any other value of x the equation is not true. By contrast, the equation sin2(x) + cos2(x) = 1 is true whatever the value of x. This is an identity.
How do I find x when it's not in the equation?
I am not entirely sure what situation you are talking about. If there is no "x" in an equation, there is no point in finding it. On the other hand, if "x" disappears when solving an equation, that's usually an indication that the equation is always true, or always false, independently of the value of "x". Example: x = x + 1 Subtracting "x" from both sides, you get: 0 = 1 Since this is false, the equation is false (for ANY value of "x"). As another example: 3x = 3x Subtracing 3x on each side, you get: 0 = 0 Since this is true, and "x" doesn't appear in it, the original equation is ALWAYS true, i.e., no matter what value "x" has.

How do you find the x value?
By moving all other values to one side and setting it equal to X. For instance, x-12=24. To find the "x" value, add 12 to both sides of the equation which will result in x=36. We know that x=36 is true because when we "plug-in" or "substitute" every "x" in the original equation with the value "36", we should get matatically true statements. For instance 36-12=24 is a true statement.
An equation for a line in the xy-plane allows you to find the value of y given x?
True.
An equation for a line in the xy-plane allows you to find the value of ygiven x?
TRUE
What is an equation that is true for every value?
how about X = X
Why are some equations called identites?
That means that they are always true. For example: x + x = 2x is true for ANY value of "x", so it is an identity. In contrast, x + 2 = 5 is only true for one specific value of "x", so it is not an identity.
Equation that is not true for any value?
x - 1 = x + 1
Find the value of 2x² when x equals 3?
18
What value of x makes the sentence true x+8=17?
18
What value of x is 1 divided by x equal x percentage a true sentence?
so you are asking: When does 1/x = x% become true? It doesn't make sense. 1/x = x is true when x = 1 But it is never true with the percentage sign at the end.
What is the value for a variable that makes an equation?
It's the value that when substituted in for the variable, makes the equation true. Ex: x + 1 = 3 The value 2, when substituted for the variable x, makes the equation true.
