Question

Solve the system using the method of your choice.
3x+y=−12x−y=−8

Answer 1

Answer: x=-5,y=3

Step-by-step explanation: Add the 2 equations together, 3x+x=4x, y+(-y)=0, and -12-8=-20. This leaves us with 4x=-20, so x=-5. Plug x back into the equation, so -5-y=-8, add 5 to both sides so -y=-3, and y=3.
