ANSWER
The solution is
x=-3,y=-2
EXPLANATION
First equation
3x – 3y = –3
Second Equation:
5x – y = –13
Multiply the second equation by 3 to get:
Third equation:
15x-3y=-39
Subtract the first equation from the third equation:
Divide both sides by 12,
Put x=-3 into the first equation:
Group like terms,
The solution is
x=-3,y=-2
D∩E=D This is because since D is a subset of E then the elements they will have in common are the elements in D and D is not a null set
