Works well. Had some issues with conversion time at first, seems to work well. Also had a few issues where the recipient of a PDFfiller email document, could not open the document. The problem may have been on their end. I just forwarded in a separate email. Great service and business tool. Thank you, Jim Kelly Fechheimer Brothers Company

Addition Method. Adding the equations means that we add the left sides of the two equations together, and we add the right sides together. This is legal because of the Addition Principle, which says that we can add the same amount to both sides of an equation.

Addition Method. Adding the equations means that we add the left sides of the two equations together, and we add the right sides together. This is legal because of the Addition Principle, which says that we can add the same amount to both sides of an equation.
Step 1: Multiply each equation by a suitable number so that the two equations have the same leading coefficient. Step 2: Subtract the second equation from the first. Step 3: Solve this new equation for y. Step 4: Substitute y = 2 into either Equation 1 or Equation 2 above and solve for x.
When a system has no solution or an infinite number of solutions, and we attempt to find a single, unique solution using an algebraic method, such as substitution, the variables will cancel out, and we will have an equation consisting of only constants. If the equation is untrue then the system has no solution.
The method of solving “by substitution” works by solving one of the equations (you choose which one) for one of the variables (you choose which one), and then plugging this back into the other equation, “substituting” for the chosen variable and solving for the other.
The three methods most commonly used to solve systems of equation are substitution, elimination and augmented matrices.
