Hi, I'm new to Mathematica and I feel like this is a stupid question but I can't seem to define more than one constant If I type SetAttributes[a,b,c,Contstant] I get SetAttributes::argrx: SetAttributes called with 4 arguments; 2 arguments are \expected. I have three equations and three variables I want to solve for and I have 8 constants. x+y+z=1 b*x+c*y+d*z=A f*x+g*y+h*z=Q b,c,d,A,f,g,h,Q are constants and I want a generic equations that I can use for many different variations of these constants. I've done the calculation by hand but fear I have made a mistake and would like to double check my calculation, and then use the equation to propagate my errors, as each constant has an associated standard error of the mean. Propagation of my error will give me an error on my model calculation, which is really important. Thanks
