a number exceeds another number by 5.the sum of the numbers is 19. find the smaller number ?
Correct answer: C. 7
- A. 5
- B. 6
- C. 7
- D. 12
Explanation
Let the smaller number be x, so the larger number is x + 5. Their sum gives x + (x + 5) = 19, so 2x = 14 and x = 7. The likely mistake is choosing 12, which is the larger number rather than the smaller one.

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.
