Here, the sign between LHS and RHS of the expression is not an equal sign. We use concepts of mathematics everywhere, every day, almost in every situation. What is the reasoning behind nighttime restrictions during pandemic? Algebra is another interesting branch where we express our daily life situations in the form of numbers and letters (variables). The main purpose of solving algebraic equations is to find the unknown variable in the given expression. $linksRecArr["alias_link_id"] . "" $activeLevel . However, when I checked my answer, the correct answer should be, Any assistance would be greatly appreciated, First, to show the desired equality, we have: $$\frac{x^2-3x}{x^2-9}=\frac{x^2-9-3x+9}{x^2-9}=\frac{x^2-9}{x^2-9}-\frac{3x-9}{x^2-9}=1-\frac{3x-9}{x^2-9}.$$, Now, assuming that you are trying to find the integral of $\dfrac{x^2-3x}{x^2-9}$, we have: if($linksRecArr["alias_link_level"] == 1 && $linksRecArr["alias_link_id"] == (int)$_GET["sll1_id"]) $fldNameConvertTxt = ""; The latter reports the number of parts on the LHS and RHS, respectively. Mathematics Stack Exchange is a question and answer site for people studying math at any level and professionals in related fields. $thisLinkName = $linksRecArr["alias" . "_link_name"]; This is also a good way of showing LHS = RHS. Few examples of expressions are as follows: The equation is an expression where two sides of the expression are connected through an equal to sign (=). "./" : $linksRecArr["alias" . $siteFolderZone = ""; So, we can see that both have equal values/expressions and therefore we can conclude that LHS = RHS. An algebraic equation contains two algebraic expressions which are separated by an equal sign (=) in between. It is a special branch of mathematics which deals with numbers, shapes and letters.

Should I have instead transformed the LHS into RHS without bringing anything from LHS to RHS and vice versa? We can form a variety of expressions using a combination of different variables and numbers. $thisLinkName = $linksRecArr["alias" . "\n"; In combining like terms, the variables with the same degree are gathered together and the constant terms are separated, for performing the simplification process. }
