Explanation Given: 4 x − 3 − 1 x Concept Used: To check if the given problem is an equation or an equation we have to look for “ equals to ” if there is an = sign in problem then it is an equation, otherwise it’s an expression To add/subtract rational expressions with unlike denominator find LCD(least common divisor) of denominators convert each rational expressions as an equivalent fraction whose denominator is the LCD Add/subtract the like rational expressions To simplify a given expression, we have to find the common factor of the numerator and denominator and then divide them by the common factor. Calculation: To check whether 4 x − 3 − 1 x is an equation or an expression we have to look for “ equals to ” if there is an = sign in problem then it is an equation, otherwise it’s an expression, as there is no equals to sign in 4 x − 3 − 1 x hence it’s an expression Now, to perform the operation in 4 x − 3 − 1 x which is subtraction, first see as the LCD of denominators in given rational expression ( x and x − 3 ) is x ( x − 3 ) , thus write each rational expression as an equivalent rational expression whose denominator is x ( x − 3 ) , thus 4 x − 3 ⋅ x x = 4 x x ( x − 3 ) , 1 x ⋅ x

Equations and Inequations

Equations and inequalities describe the relationship between two mathematical expressions.

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
