If 2x + 2y = 8; 2x - y = 2; 2x - 5y + k = 0 are concurrent, then what is the value of k ?
ANSWERS
Concurrent means that they meet at a common point.
Solve, 1st 2 equations in order to find the values of x and y.
I think, it is x = 2, y = 2
Now put this value in the 3rd equation, to get the value of k.
