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.

What is the formula to find x value?
The formula to find the value of X would be Y-2X. This would equal to y-9 times 2 X.
What does x mean in a math equation?
x is a variable. You do not have to know what its value is. In that equation you have to find the value of x, so if you already know what x stands for then you know the answer
How do you find the absolute value of something?
If a number is not less than zero then that is its absolute value. If a number is less than zero, its negative is its absolute value. So, if |x| denotes the absolute value of x, then |x| = -x for x<0 [since if x<0 then -x>0] and |x| = x for x>= 0
How do you find the period of tangent function?
You find the smallest positive value y such that tan(x + y) = tan(x) for all x.
X2 equals 5 find the value x?
x=5/2 or 2.5
