Dearing author: I am a student. I am a beginner in learning R-project. I have a queation!! If we want to solve following equation, how can i do first?? We want to solve X's and Y's value!! When we have two equation: For example: 2X+3Y=5 X+Y=2 I just take a simple example!! MY form is more difficult than above example!! Please help me!! And give me a reference to solve it!! THANK YOU!!

Check out ?solve: m <- matrix(c(2,1,3,1),2) # create 2x2 matrix b <- c(5,2) solve(m,b) .... <at> tknet.tku.edu.tw> writes: : : Dearing author: : I am a student. : I am a beginner in learning R-project. : I have a queation!! : If we want to solve following equation, how can i do first?? : We want to solve X's and Y's value!! : When we have two equation: : For example: : : 2X+3Y=5 : X+Y=2 : : I just take a simple example!! : MY form is more difficult than above example!! : Please help me!!
