Computing Matrix Algebra with R and Rcpp

Challenge: System of Linear Equations

Practice solving a system of linear equations by writing R code that applies matrix algebra techniques. This lesson helps you build computational skills essential for machine learning and data processing using R and C++.

We'll cover the following...

Exercise

Use the code editor below to write the R code required to solve the following system of linear equations:

0∗x1 + 2∗x2 + 3∗x3=05∗x1 + 0∗x2 + 1∗x3=11∗x1 + 4∗x2 − 2∗x3=3\begin{alignat}{2} 0 * x_1 \space + \space 2 * x_2 \space + \space 3 * x_3 = 0 \\ 5 * x_1 \space + \space 0 * x_2 \space + \space 1 * x_3 = 1 \\ 1 * x_1 \space + \space 4 * x_2 \space - \space 2 * x_3 = 3 \\ \end{alignat} ...
