An equation is a mathematical statement that asserts the equality of two expressions.[1] Equations consist of the expressions that have to be equal on opposite sides of an equal sign, as in
x + 3 = 5.\,
An equation is a mathematical statement that shows the equality of two expressions. It consists of an equals sign (=) between the two expressions, with the expression on the left side called the left-hand side (LHS) and the expression on the right side called the right-hand side (RHS). The goal of an equation is to find the value(s) of the variable(s) that make the LHS equal to the RHS.
To understand and solve an equation, you typically follow these steps:
1. Identify the variable: Look for the letter or symbol that represents the unknown quantity in the equation.
2. Simplify both sides: Simplify or perform any necessary operations (addition, subtraction, multiplication, division) on each side of the equation to eliminate any parentheses, exponents, or fractions and make it easier to solve.
3. Isolate the variable: Move all terms containing the variable to one side of the equation and move all constant terms to the other side. This is typically done by using inverse operations (the opposite of the operation in the equation) to cancel out terms on each side.
4. Solve the equation: Perform the necessary steps to find the value(s) of the variable that satisfy the equality between the LHS and RHS. This may involve further simplification, factoring, or substitution.
5. Check your solution: Substitute the found value(s) back into the original equation to ensure that it satisfies the equation. If it does, then the solution is valid; otherwise, you may need to recheck your steps.
By following these steps, you can solve equations and determine the values of variables that satisfy the given conditions.
