I need help can I have how to do it and some work so I can do it.

Answer:

(-1,-2) OR x = -1 and y = -2

Step-by-step explanation:

y = 3x + 1

y = -x -3

so you would first multiply everything on y = -x -3 by 3 and get 3y = -3x -9

so then you would add 3y = -3x -9 to y = 3x + 1 ( to eliminate the x )which would be 4y = -8 then divide by 4 and get y = -2

then you plug in y = -2 into any one of the equations but to make it easier i am going to plug it into y = -x -3 so now it would be -2 = -x - 3 then, add 2 to both sides which would be 0 = -x -1 then add 1 to both side 1 = -x then multiply both sides by -1 and get x = -1

SO your answer would be (-1,-2) OR x = -1 and y = -2 ( both of them are correct but it depends on what the teacher taught you)
