Two step equations

Two-step equations

Equations that require two operations to isolate the variable.

Inverse operations

Operations that undo each other, such as addition and subtraction.

Rule of balance

The principle that states you must perform the same operation on both sides of an equation to maintain equality.

Coefficient

A numerical factor in a term of an algebraic expression, often multiplying the variable.

Checking the receipts

The process of substituting the solution back into the original equation to verify its correctness.

Handling fractions in equations

Treated as division problems to simplify the solving process.

Farther number

Refers to the number that is farther from the variable in the equation, which needs to be addressed first.

Common mistakes with negative coefficients

Errors that arise when incorrectly applying operations with negative numbers during isolation of the variable.
