when dealing with modulus we have asses both the option.
1. positive case:
1 -x = 6
-x = 5
x= -5
2. negative case
-1 + x = 6
x = 7.
3. positive case .
2y - 6 = 10
y = 8
4. negative case .
-2y + 6 = 10
y = -2.
So , we will have 4 sets of values of xy.
1. -5 *8 =-40
2. -5 * -2 = 10
3. 7*8 =56
4 7* -2 = -14
So, the correct answer is a,b,d.
