Direction: In each of these questions, two equations are given. You have to solve these equations and find out the values of x and y and Give answer
( 1 ) if x < y
( 2 ) if x > y
( 3 ) if x ≤ y
( 4 ) if x ≥ y
( 5 ) if x = y

- 5
Correct Option: C
According to question , we have
From equation Ⅰ. 8x2 + 6x - 5 = 0
⇒ 8x2 + 10x − 4x − 5 = 0
⇒ 2x(4x + 5) − 1(4x + 5) = 0
⇒ (2x − 1)(4x + 5) = 0
⇒ x = | , - | ||
⇒ 12y2 − 16y − 6y + 8 = 0
⇒ 4y(3y − 4) − 2(3y − 4) = 0
⇒ (4y − 2)(3y − 4) = 0
⇒ y = | , | ||
