  • What is a linear equation?
    A linear equation is formed by setting a linear expression equal to a value, creating an equation that can be solved for the variable.
  • How do you isolate the variable in a linear equation?
    You isolate the variable by performing operations such as addition, subtraction, multiplication, or division on both sides of the equation.
  • What must you always do to both sides of a linear equation when solving?
    You must perform the same operation to both sides of the equation to maintain equality.
  • What is the opposite operation of addition when solving equations?
    The opposite operation of addition is subtraction.
  • What is the opposite operation of multiplication when solving equations?
    The opposite operation of multiplication is division.
  • What is the first step when solving a linear equation with fractions?
    The first step is to multiply every term by the least common denominator (LCD) to eliminate the fractions.
  • Why do we use the least common denominator (LCD) when solving equations with fractions?
    We use the LCD to clear all fractions, making the equation easier to solve.
  • What is a conditional equation?
    A conditional equation is a linear equation that has exactly one solution.
  • What is an identity equation?
    An identity equation is a linear equation that is true for all real numbers, meaning it has infinite solutions.
  • What is an inconsistent equation?
    An inconsistent equation is a linear equation that has no solution because it leads to a false statement.
  • How is the solution set of a linear equation with one solution written?
    It is written in set notation as the solution value inside curly brackets, for example, {3}.
  • How is the solution set written for an equation with infinite solutions?
    It is written as all real numbers, often denoted by the symbol ℝ.
  • How is the solution set written for an equation with no solutions?
    It is written as the empty set, represented by curly brackets with a slash through a zero: {∅}.
  • What is the final step after solving a linear equation?
    The final step is to check your solution by substituting it back into the original equation to verify it makes the equation true.
  • What do you call the value that makes a linear equation true?
    It is called the solution, root, or answer of the equation.
