Answer 1

Answer:

Step-by-step explanation:

Answer:

Let 1/y = a

∴ 4x + 6a = 15 (Multiply by 4) ⇒ 16x + 24a = 60(eq.1)

  6x - 8a = 14 (Multiply by 3) ⇒ 18x - 24a = 42 (eq.2)

eq.1 + eq.2 ⇒ 34x = 102

x = 3

∴12+6a = 15

∴ a = 1/2 ⇒ 1/y = 1/2 ⇒ y = 2

∴ y = px-2 ⇒ 2 = p(3)-2

∴3p-2 = 2, 3p = 4, p = 4/3

Thus, p = 4/3
