## A Worked example to illustrate how the solve calculator Works:

An equation is a mathematical expression that equates two objects. Ideally an equation consists of two mathematical expressions separated by an equal sign. In algebra, equations are vital as they help us solve for the unknown.

Examples of math equations with unknowns:

3x-4=0

3y-2x=0

In either of the examples the alphabet characters represents the unknown or variables. In order to solve an equation, you need to have the right solution strategy.

A solution method depends on the number of unknowns with respect to the number of equations. For example solving an equation with two unknowns requires you to have a system of at least 2 equations (for linear equations). On the other hand, solving a nonlinear equation might be a more complicated affair. This equation calculator helps you solve quadratic equations efficiently.

The most popular equation types are the linear equations and non-linear equations of degree two also known as quadratics.

## Solving a single variable linear equation

Best solution strategy is through factorization. This method requires you to factor the variable on the LHS of the equation while you let the constant terms be on the RHS of the equation.

Example:

2x-4+x=10

2x+x-4=10

3x=10+4

3x=14

x= \frac{14}{3}
