Assoli18 [71]3 years ago
6 0
Lets solve our system of equations step by step:
y=2x-1 equation (1)
3x-y=-1 equation (2)

Step 1. Replace equation (1) in equation (2)
3x-y=-1
3x-(2x-1)=-1
3x-2x+1=-1
x=-2 equation (3)

Step 2. Replace equation (3) in equation (1)
y=2x-1 
y=2(-2)-1
y=-4-1
y=-5

We can conclude that the correct answer is: <span>A (−2, −5) </span>
