If I put these 2 lines into wolframalpha.com it comes up with a solution
x = 1 + 2t , y = 2 – t , z = t ; x = -2 – s , y = 3 + 3s , z = 1 + 4s
t = -8/5 and s = 1/5 using equations for x & y
Solution; x = -11/5 y = 18/5 z = 9/5But the z values do not match so how can these lines intersect ?
Thanks for your input
