Answer
One Solution: (-1, -2)
Work Step by Step
Our two equation are:
1. y=x-1
2. y=-3x-5
We can use substitution and set the two equations above equal to each other because both equations equal to y.
x-1=-3x-5 (Add 3x to both sides)
4x-1=-5. (Add 1 to both sides)
4x=-4 (Divide by -4 from both sides)
x=-1
Now that we know the value of x, lets plug it into our first equation to find the value of y.
y=-1-1
y=-2
So our solution is (-1, -2)
