Algebra Equations

Algebra equations are the equations of the form algebraic variables with some numerical co-efficient. Algebra equation contains the terms like numbers, integers, fractions, roots, exponents, ratios, graphing etc. Pre algebra equation is the simple equation which can be solved easily without any complex calculations. Linear equation is an algebraic equation in which each term is either a constant or the product of a constant and with a single variable. It contains one or more variables. It occurs with great regularity in applied mathematics.

Example on how to solve algebra equations:

Solve Algebra equation 2x + 4 = 0

2x + 4 = 0

2x = - 4

x = $\frac{-4}{2}$

x = -2

Algebra equation solver is to solve the equation and to get the value of variables. The following are the important things that need to be noted down in algebra equations

Variables:

The variable is the important thing that needs to be considered in equations.

Operations:

Operations such as (+, -, x, /) are the operations that plays an important role solving equations.

Values:

We should enter the correct and valid values to get a perfect answer in solving equations.

Solve x + 3 = 0

To get the value x send +3 to other side, we get x = -3.

Therefore, x is -3.

It is very simple. It only deals with whole numbers in the above example.

Below are the examples on solving algebraic equations:

Example 1:

Solve 2x + 12 = 0

Put all the variables on one side and values on other side.

We get, 2x = -12

Now to get x value divide both sides with 2

$\frac{2x}{2}$ = $\frac{-12}{2}$

x = -6

2) Solve the equation x² - 4 = 0

x² - 4 = 0

Add 4 on both the sides we get,

x² = 4

To avoid a square put square root on both the sides

x = √4

x = 2

Example 2:

Solve 5x + 4 = 3x + 10

Solution: 5x + 4 = 3x + 10

Put all the variables on one side and value on other side.

We get, 5x - 3x = 10 - 4

2x = 6

Now to get x value divide both sides with 2

$\frac{2x}{2}$ = $\frac{6}{2}$

x = 3
