Solving algebra problems
something In other words, we want to move everything except "x" (or whatever name the variable has) over to the right hand side. In this case x 6 is the only solution. You can usually find the exact answer or, if necessary, a numerical answer to almost any accuracy you require. How to Solve an Equation There is no "one perfect way" to solve all equations. Statistics, finite Math, linear Algebra, chemistry, graphing.
To start another set of problems, press "reset". Special Equations There are special ways of solving some types of equations. Problem 9: Find the equation of the line that passes through the points (-1, -1) and (-1, 2). Once you have finished, press "finish" and you get a table with your answers and the right answers to compare with. Maximize the window obtained. The graphs section contains commands for alphabet writing paper plotting equations and inequalities. Example: Solve 3x6 9 Start with:3x6 9 Add 6 to both sides:3x 96 Divide by 3:x (96 3 Now we have x something, and a short calculation reveals that x 5 Like a Puzzle In fact, solving an equation is just like solving a puzzle. You might like to practice solving some animated equations. More Algebra Problems - Applet click on the button above "click here to start" to start the applet and.
You can also plot inequalities in two variables. Let me take a look. How To Check Take the solution(s) and put them in the original equation to see if they really work. It will have an equals sign " like this: x 2 4, that equations says: what is on the left (x 2) is equal to what is on the right (4).
