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 ) x < y
( 2 ) x > y
( 3 ) x ≤ y
( 4 ) x ≥ y
( 5 ) x = y

Correct Option: E
As per the given above equations , we can say that
Ⅰ. 4x + 7y = 209 ....................( 1 )
Ⅱ. 12x – 14y = –38 ...................( 2 )
Now, (1) × 2 + (2), we have
12x – 14y = –38
8x + 14y = 418
⇒ 20x = 380
| ∴ x = | = 19 | |
4 × 19 + 7y = 209
or, 7y = 209 – 76 = 133
| ∴ y = | = 19 | |
