Hi, I'm new to Maple and have been trying to solve the below curve intersection. But the answer I am getting from Maple is incorrect and does not tally with the plot when drawn on excel, am I doing something wrong ???  (the intersect should be around x=93.9)

 

restart;
eq1:=y=86:
eq2:=y=-0.0000054527x^3+0.010903836x^2+0.0714244709x+74.18816:
sol:=solve({eq1,eq2},{x,y});
