What are like terms?

Back

Like terms are terms in an algebraic expression that have the same variable raised to the same power. For example, in the expression 3x + 4x, both terms are like terms because they both contain the variable x.

Front

What is a coefficient?

Back

A coefficient is a numerical factor in a term of an algebraic expression. For example, in the term 5x, 5 is the coefficient.

Front

What are inverse operations?

Back

Inverse operations are pairs of operations that undo each other. For example, addition and subtraction are inverse operations, as are multiplication and division.

Front

What is a term in an expression?

Back

A term is a single mathematical expression that can be a number, a variable, or a combination of both, separated by addition or subtraction. For example, in the expression 3x + 4, both 3x and 4 are terms.

Back

Subtraction is needed to isolate x. You would subtract 6 from both sides to solve for x.

What is the difference between an equation and an expression?

Back

An equation is a statement that two expressions are equal, while an expression is a combination of numbers, variables, and operations without an equality sign.

What is the purpose of using inverse operations in solving equations?

Back

Inverse operations are used to isolate the variable on one side of the equation, making it easier to solve for that variable.
