Figured someone might know something I didn't. I have been doing practice problems and getting them wrong and see the process for the right answer. Yet I still do not understand some methods. I don't understand the formulas they come up. Mainly when I am manipulating a formula it doesn't end up the same, or completely lost with the wording. I have done a simple Google search and foundhttp://catalog.flatworldknowledge.com/bookhub/reader/128?e=fwk-redden-ch02_s05 pretty helpful. Looking for some extra input and possibly a different way to approach these problems. Anything is helpful.phinds said:
Linear equations are mathematical expressions that involve a variable, typically represented by x, and a constant. The goal is to find the value of the variable that makes the equation true.
Linear equations are used to solve real-world problems, such as determining the cost of a product based on the number of units sold, calculating the distance between two points, or predicting future trends in data.
The first step is to isolate the variable on one side of the equation by using inverse operations. Then, simplify both sides of the equation to get a numerical answer for the variable. Finally, check your answer by plugging it back into the original equation to make sure it is correct.
Yes, linear equations can have one, infinite, or no solutions. If the equation has one solution, it represents the point where the equation's line intersects with the x-axis. If there are infinite solutions, the equation represents a line that overlaps with the x-axis. If there are no solutions, the equation represents parallel lines.
Solving linear equations can help in decision making by providing a quantitative analysis of a situation. By finding the value of the variable, you can determine the most cost-effective option, predict future trends, or make informed decisions based on data analysis.
