Solving Linear Equations

An equation is a mathematical statement that is only true for some unknown variables, usually represented by a letter such as xSolving an equation means manipulating the expressions and finding the value of the unknown variablesIn order to solve for the unknown variable, you must isolate the variable To keep an equation equal, we must do exactly the same thing to each side of the equation. If we add (or subtract) a quantity from one side, we must add (or subtract) that same quantity from the other side.
