The present invention puts forward a new method for resolving algebraic equation with one variable. Its uses the fixed functions stored in computer to make quick resolution, and after its lemma, other two series methods are obtained. By using the above-mentioned principle the following sub-...
Solving a Single Variable Equation : 5.2Solve :x = 0 Solution isx = 0 Solving a Single Variable Equation : 5.3Solveax-3x-b+1= 0 In this type of equations, having more than one variable (unknown), you have to specify for which variable you want the equation solved. ...
3) if you solve and get a NEVER TRUE equation (e.g. -2=9), then the system has no solutions Three Equations with Three Unknowns Strategy 1) pick two of the three equations and, using either substitution or elimination, eliminate one variable. 2) pick another pair of the original equat...
Your ultimate goal is to get all of the constants on one side of the equation and all of the variables on the other side of the equation. You can accomplish this by adding or subtracting terms on BOTH sides of the equation. Let's take a look at a few examples. Example 1 - Variable...
Linear equations in one variable can be used to calculate the value of an integer when we are given two or more integers with one of them being unknown. Using the expression in an equation form, we can easily find the value of an unknown integer. Linear equation helps us deduce integers ...

DEVELOPING SEVENTH GRADERS' ALGEBRAIC THINKINGON LINEAR EQUATIONIN ONE VARIABLE TOPIC This paper discusses how to develop seventh graders' algebraic thinking on linear equation in one variable. For many students in the first year of middle school, algebra is given as formal and abstract topic. Most...
Start with setting the equations equal to each other: {eq}4x=x+6 {/eq} Next, subtract x from both sides: {eq}3x=6 {/eq} Divide both sides by 3: {eq}x=2 {/eq} Substitute the value of x back into one of the original equations. Either equation can be solved to find the y ...
