Hi,

 2x-4y=-1 &   

  y=x-1  

finding the point of Intersection or the 'solution' to this system of EQs

 2x - 4y = -1

 2x - 4(x-1) = -1  |Substituting for y   y+=+x-1+

    -2x +4 = -1

     -2x = -5

       x = (5/2)  and y = (3/2)  (x-1)

Pt (5/2, 3/2) is the solution for this system of EQs (the lines intersect at that point)

2x - 4y = -1
y = x - 1

put the system of linear equations into standard form
---
2x - 4y = -1
x - y = 1
---
copy and paste the above standard form linear equations in to this solver:

answer:
the point of intersection of the two lines is:
x= 2.5
y= 1.5
