Many puzzles reduce to finding the single number that makes two expressions equal. Chapter 2, Linear Equations in One Variable, of the NCERT Mathematics textbook for Class 8 teaches a reliable method for such puzzles. You will simplify equations using the distributive law, transpose terms across the equality, handle equations with variables on both sides, and reduce some fractional forms to linear ones. Applications to ages, digits of numbers, money and perimeters show how one well-framed equation unlocks a whole problem.
