The sum of two numbers is 25 and their differenee is 13. Find their product :

Correct answer: B. 114

  • A. 104
  • B. 114
  • C. 315
  • D. 325

Explanation

Let the numbers be x and y. From x + y = 25 and x - y = 13, adding the equations gives 2x = 38, so x = 19 and y = 6; their product is 19 x 6 = 114. The likely mistake is choosing 104, which comes from using incorrect numbers instead of the pair with sum 25 and difference 13.

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.
