The sum of the digits of a two-digit number is 12. The difference of the digits is 6. Find the number?

Correct answer: E. Either (a) or (b)

  • A. 93
  • B. 39
  • C. 75
  • D. 48
  • E. Either (a) or (b)

Explanation

Let the digits be a and b. Then a + b = 12 and their absolute difference is 6, giving the digit pair 9 and 3; because the order is not specified, both 93 and 39 satisfy the conditions. A likely mistake is choosing only option a or b and assuming the larger digit must come first.

About Linear Equations

Linear equations contain variables only to the first power and produce straight-line relationships when represented graphically. Problems involve solving equations with brackets, fractions, and variables on both sides, forming equations from statements, and handling simultaneous linear equations, which differ from quadratic equations by having no squared variable.
