Linear system

Dear R-help

I have a problem solving a linear system like

353a+45b+29c=79
45a+29b+3c=5
29a+3b+4c=8

Is there any way of doing this in R?

Best Regards
Jim

Use ?solve:

X <- matrix(c(353, 45, 29,
                45, 29,  3,
                29,  3,  4), 3, 3, byrow = TRUE)
y <- c(79, 5, 8)
b <- solve(X, y)

Have you read the posting guide? In particular, have you tried simple 
queries using help.search or the R archives? This question has been 
answered many times.
