Answer :
Question 1 = A
Question 2 = B
Question 3 = E
Question 4 = C
Question 5 = E
Solutions :
Question 1 :
x = 6, 5
y = 12 , 10
Put All Value on single line, Then check Relation Bewteen Variables x and y
Question 2 :
x = 20,5
y = 5 , 6
Put All Value on single line, Then check Relation Bewteen Variables x and y
Question 3 :
x = 2 , -1
y = 4, -3
Put All Value on single line, Then check Relation Bewteen Variables x and y
Question 4 :
x = -7 , -3
y = -9 , -7
Put All Value on single line, Then check Relation Bewteen Variables x and y
Question 5 :
x = 9 , 8
y = 18 , 3
Put All Value on single line, Then check Relation Bewteen Variables x and y
