How to Solve One-step Equations Step 1: Note down the equation. For example. ... Step 2: Isolate the variable. You must conduct an inverse operation to cancel the constants in order to isolate a variable, on one side of the equation. ... Step 3: Adding or subtracting the constant from both sides. ... Step 4: Verify your solution.

We have to do the same thing to both sides whatever you do to one side you have to do to the other. So we added six to the left.

We have 4 ways of solving one-step equations: Adding, Substracting, multiplication and division. If we add the same number to both sides of an equation, both sides will remain equal. If we subtract the same number from both sides of an equation, both sides will remain equal.

We check a solution to an equation by replacing the variable in the equation with the value of the solution. A solution should result in a true statement when simplified.

Note: To determine if an equation is a linear function, it must have the form $y = mx + b$ (in which m is the slope and b is the y-intercept). A nonlinear function will not match this form. In a linear equation, the variables appear in first degree only and terms containing products of variables are absent.

The Relationship Between a CDF and a PDF In technical terms, a probability density function (pdf) is the derivative of a cumulative distribution function (cdf). What is this? Report Ad. Furthermore, the area under the curve of a pdf between negative infinity and x is equal to the value of x on the cdf.

Let X be a continuous random variable with pdf f and cdf F. By definition, the cdf is found by integrating the pdf: F(x)=x222b2212221ef(t)dt. By the Fundamental Theorem of Calculus, the pdf can be found by differentiating the cdf: f(x)=ddxF(x)
