Answer:
There is 1 solution (1,0)
Step-by-step explanation:
y = 3.5x − 3.5
y = −3.5x + 3.5
Add this system of equations together
y = 3.5x − 3.5
y = −3.5x + 3.5
-----------------------
2y = 0
y = 0
Substitute back in
0 = 3.5x - 3.5
Add 3.5 to each side
3.5 = 3.5x
Divide by 3.5
3.5/3.5 = 3.5x/3.5
1=x
There is 1 solution (1,0)
