How to Solve Algebra
Algebra is the branch of mathematics that uses symbols (variables) to represent numbers in equations. Solving for a variable involves isolating it on one side of the equation.
Isolate the Variable
Move all terms with 'x' to one side and constants to the other.
Inverse Operations
Use subtraction to undo addition, and division to undo multiplication.
Pro Tip
Always perform the same operation on both sides of the equal sign. If you add 5 to the left, you must add 5 to the right to keep the equation balanced.
Common FAQ
What is a linear equation?
A linear equation is an algebraic equation in which each term is either a constant or the product of a constant and a single variable.
Why is 'x' used in algebra?
Historically, 'x' was used by printers and early mathematicians to represent an unknown value, derived from Arabic words meaning "thing".
