Rational equations have a variable in the denominator in at least one of the terms. Our goal is to perform algebraic operations so that the variables appear in the numerator. In fact, we will eliminate all denominators by multiplying both sides of the equation by the least common denominator ...
But for solving simple inequalities (linear), we usually apply algebraic operations likeaddition,subtraction,multiplication, anddivision. Consider the following example: 2x + 3 > 3x + 4 Subtracting 3x and 3 from both sides, 2x - 3x > 4 - 3 ...

We know how frustrating the solving of algebraic equations can be - we hope that our site will provide you with some useful methods and simple hints in this area of algebra. Currently our help tutorials cover solving linear equations, solving quadratic equations, solving radical equations, solving...
When solving linear trigonometric equations, we can use algebraic techniques just as we do solving algebraic equations. Look for patterns, like the difference of squares, quadratic form, or an expression that lends itself well to substitution. Equations involving a single trigonometric function can be...
Functions that are the result of the division of two polynomials are rational functions, which can be solved by cross multiplying numerators and denominators. Review the definition of a rational function and learn how to solve rational equations and rational inequalities. ...
