Option 4 is correct
Step-by-step explanation:
Given: The system of inequality


We need to choose correct option.
Option 1: (-5,2)
Put x=-5 and y=2
Equation 1 Equation 2


TRUE FALSE
Option 2: (2,2)
Put x=2 and y=2
Equation 1 Equation 2


FALSE FALSE
Option 3: (5,2)
Put x=-5 and y=2
Equation 1 Equation 2


FALSE TRUE
Option 1, 2 and 3 are incorrect because both equation must be true for solution.
Hence, Option 4 is correct no solution.
(2+3)^2-16÷2 is equal to 17
