if x < y

if x ≤ y

ঙ)

if x = y or the relationship cannot be established.

According to the given equations, I. 121x 2 – 17 = 8 ⇒ 121x 2 = 8 + 17 = 25 ⇒ x =

\sqrt {\frac{{25}}{{121}}}

∴ x = ± 5/11 II.

13y + \sqrt 9 = \sqrt {64}

⇒ 13y + 3 = 8 ⇒ 13y = 8 – 3 = 5 ∴ y = 5/13 ∵ The value of y is greater than -5/11 but less than 5/11 Hence, no relationship can be established

\frac{a}{3} = \frac{b}{4} = \frac{c}{7}

\frac{{a + b + c}}{a}

{P^2} + {1 \over {{P^2}}} = 7

{P^2} - {1 \over {{P^2}}}.

Direction:In the following questions two equations numbered I and II are given. You have to solve both the equations and find relation between x and y. I. 121x2– 17 = 8 II. 13y+9=6413y + \sqrt 9 = \sqrt {64}13y+9​=64​
