Study online linear equations
Introduction :
Linear equations are one of the first concepts students on learn pre algebra or algebra class. These problems are the foundation for more advanced mathematics on concepts, and they are also found in many everyday situations where an unknown value or measurement is needed. Learning linear equation starts with mastering of basic pattern . Once a student understands the pattern, these problems become manageable, if matter how challenging they might initially appear.
Definition linear equation
A linear equation is an algebraic equation in which each terms or either a constant or the product of a constant a single variable.
Linear equations can have one or more variables. Linear equations occur us great regularity in applied mathematics. While they arise quite naturally when modeling many phenomena,if they are particularly useful since many non-linear equations may be reduced to linear equations by assuming that quantities of interest vary to only a small extent from some background state.

How to Learn Linear Equations
- Simplify the equation by performing any math can be done as the equation stands. For example, simplify 3x + 2 + 4 = 12 by adding the 2 and 4 together, yielding 3x + 6 = 12.
- Look at the equation and decide, what is being done of variable. In the example of 3x + 6 = 12, x is being multiplied by three and increased by six.
- Isolate the variable. Start by performing the opposite operation,if on the equation for any addition or subtraction in the problem. For this example, remove the plus than six by subtracting six from the equation, performing the operation on both sides of the equals sign to keep the equation balanced. (3x + 6 -- 6 = 12 -- 6, which gives 3x + 0 = 6 or 3x = 6)
- Continue by performing the opposite operation on any multiplication and division ,if being done to the variable. In this example, divide both sides by 3. (3x/3 = 6/3)
- Solve the equation for the variable. (x = 2)
- Check the equation by plugging the value, and than variable into the original equation. In this example, 3 x 2 + 2 + 4 does equal 12, so the answer is correct.
