Question
By interchanging the given two signs and numbers which
of the following equation will be correct? × and ÷, 7 and 9Solution
The correct answer is A
I. 7x + 8y = 36
II. 3x + 4y = 14
(i) 2x² + 14x - 16 = 0
(ii) y² – y – 12 = 0
l. x2 - 16x + 64 = 0
II. y2Â = 64
I. 6x2 + 23x + 10 = 0
II. 2y2 - 3y - 5 = 0
I. 8/(21x) - 2/7 = 0
II. 16y² - 24y +9 = 0
In the question, two equations I and II are given. You have to solve both the equations to establish the correct relation between x and y.
I. x
I. x2 + 13x + 42 = 0
II. y² + 13y + 40 = 0
I. 2y² - 35y + 132 = 0
II. 2x² - 31x + 110 = 0
I. 195x² - 46x - 21 = 0
II. 209y² + 13y - 12 = 0
I. x2 + 16x + 63 = 0
II. y2 + 2y - 15 = 0
