Question

find the equation of the circumcircle of the triangle formed by the straight lines given in each of the following 2 X + y =4 ,x + y =6, X + 2 y = 5​

Answer 1

Answer:

1) 2x+y=4

2x+x=4

x=4/3

x=1.33

2) x+y=6

2x=6

x=6/2

x=3

3) x+2y=5

3x=5

x=5/3

x=1.66

since if there is any two different variables we can change them into same variables
