Re 6.0.2 under WinXP.

This code's output is strange:  what does 0.-7.9424 g mean?  Ditto for all values returned by Solve.

Thankx.

Bruce


{x[0],y[0]}={10.5,6.08};
{x[1],y[1]}={3.23,14.4};
{x[2],y[2]}={18,12.7};
m=16.1;

Solve[{a+c==0,b+d==m*g,d(x[2]-x[0])==c(y[2]-y[0]),a(y[1]-y[0])==b(x[1]-x[0])},{a,b,c,d}]

Out[11]= {{a->0.-7.9424 g,b->0.+9.08951 g,c->0.+7.9424 g,d->0.+7.01049 g}}
