I'm new to Mathematica. I have to say, it's making me crazy. I want to solve a system of four simultaneous equations in four variables and then have the numerical solutions applied to those variables from the rules so that, in this case,
m=127, b=7,f=14.5588, t=148.559:
solutions =
Solve[m == 127 && b == 7 && f == 0.098*t && m + b + f == t, {m, b, f,
t}]
Then I want to set m, b, t, and f to the values in the rule assignment. I've tried every permutation I can think of of Part and ReplaceAll, but I either get an error or I get m=m, b=b, etc. It really shouldn't be that difficult, it seems like something users would want to do all the time. I see Stack Exchange with obscure code using @@@, and other stuff. Is there not just a simple way to solve a set of simultaneous equations and assign the results to the variables in the equations?
