y=2x+y and 3x+y=16
System of equations?

Answer:
Good day sir
The answer is (3,7)
Step-by-step explanation:
One way is to graph the line
Another way is to do it the hard way
3x + y = 16 is y = -3x + 16
Add the original equations up and solve
2y = -x + 17
This is a start (just solve this equation) but the answer is (3,7)
