What is the value of (p) for the equations (px+10y=50) and (14x+35y=122) to have no solution?

Answer and explanation

Correct answer: 4

For two linear equations to have no solution, the ratios of the coefficients of x and y must be equal, while the ratio of the constant terms must be different. Thus, p/14 = 10/35 = 2/7, giving p = 4. Also, 50/122 = 25/61, which is not equal to 2/7, so the equations are inconsistent. Exam tip: Remember the condition a₁/a₂ = b₁/b₂ ≠ c₁/c₂ for no solution.
