Given: system%28y=x%2B1%28red%28EQN1%29%29%2Cy=2x-1%28red%28EQN2%29%29%29

In EQN 1, let Fy=0: 0=x%2B1
x=-1: Point (-1,0)
let Fx=0; y=0%2B1
y=1: Point (0,1)

The Line passes on points (-1,0) & (1,0)


In EQN 2, let Fy=0: 0=2x-1
2x=1 ---> x=1%2F2: Point (0.50,0)
let Fx=0: y=2%280%29-1%7D%7D%0D%0A%7B%7B%7By=-1: Point (0,-1)

The line passes on points (1/2, 0) & (0,-1)


We see both lines: ---> Intersect at Point (2,3)

Check, equate the two lines:
x%2B1=2x-1
1%2B1=2x-x
2=x, susbt, in EQN 1:
y=highlight%282%29%2B1
y=3
Point (2,3), solution
