Which x satisfies an equation?

Which x satisfies an equation?

What you'll learn

  • Identify whether a given value for 'x' is a solution to a one-variable equation by substituting the value and checking for equality.
  • Solve one-step linear equations involving addition, subtraction, multiplication, or division to find the value of 'x' that satisfies the equation.
  • Explain, using mathematical vocabulary (e.g., variable, equation, solution, substitute), the process of determining if a specific value for 'x' makes an equation true.
  • Apply the concept of inverse operations to isolate the variable 'x' and solve for its value in a given equation.
