Types of Algebra Equations
There are five main types of algebraic equations, distinguished by the position of variables, the types of operators and functions used, and the behavior of their graphs. Each type of equation has a different expected input and produces an output with a... More »

In mathematics, an algebraic equation or polynomial equation is an equation of the form. P = Q {\displaystyle P=Q} P=Q. where P and Q are polynomials with coefficients in some field, often the field of the rational numbers. For most authors, an algebraic equation is univariate, which means that it involves only one variable.


Learn how to solve linear equations that contain a single variable. For example, solve 2(x+3)=(4x-1)/2+7.

Algebra Calculator shows you the step-by-step solutions! Solves algebra problems and walks you through them.


where a and b are real numbers and x is a variable. This form is sometimes called the standard form of a linear equation. Note that most linear equations will not start off in this form. Also, the variable may or may not be an x so don't get too locked into always seeing an x there. To solve linear equations we will make heavy ...

Example: x − 2 = 4. When we put 6 in place of x we get: 6 − 2 = 4. which is true. So x = 6 is a solution. How about other values for x ? For x=5 we get "5−2=4" which is not true, so x=5 is not a solution. For x=9 we get "9−2=4" which is not true, so x=9 is not a solution. etc. In this case x = 6 is the only solution.
