  2 Systems of linear equations Matrices first arose from trying to solve systems of linear equations. Such problems go back to the very earliest recorded instances of mathematical activity. A Babylonian tablet from around 300 BC states the following problem1: There are two fields whose total area is 1800 square yards. One produces grain at the

  This method uses symbolic regression [i.e., genetic programming (5)] to find nonlinear differential equations, and it balances com-plexity of the model, measured in the number of terms, with model accuracy. The resulting model identification realizes a long-sought goal of the physics and engineering communities to discover dynamical systems ...

In this problem, we avoid fractions by choosing the first equation and solving for y in terms of x: 5x + y = 4 Solve the first equation for y in terms of x. y = 4 - 5x Substitute into the second equation.
