Question

For integers x and y, the inequality is satisfied, find
sum of x+y.


$3 \sqrt{4x + 5y + 7} + 5 \div 3x - 4x + 61 \leqslant 4$
​

Answer 1

Step-by-step explanation:

ANSWER

4x+5y=7 ......(1)

3x+4y=5 ......(2)

4×(2)−3×(3)

12x+16y−12x−15y=20−21

y=−1

Substitute y=−1 in (1) we get

4x+5×−1=7

⇒4x=7+5=12

or x=

4

12

=3

∴x=3,y=−1
