Dear All

I have updated my Maple 18, I am surprised to see that ordinary "solve" do not work and return error massage like;

"Error, (in coulditbe) invalid input: `coulditbe/internal` uses a 1st argument, obj, which is missing"

or like;

"Error, (in solve) invalid input: hastype expects 2 arguments, but received 1"

I am totally confused !!!

Can anybody help me out please !!!!

 

 


> 

solve({x+2*y = 3, y+1/x = 1}, [x, y])

Error, (in coulditbe) invalid input: `coulditbe/internal` uses a 1st argument, obj, which is missing

Error, (in solve) invalid input: hastype expects 2 arguments, but received 1
