Systems of Equations

Many of the later elements end in the same step: several conditions must hold at once, and the answer is the point that satisfies all of them. A market clears where supply equals demand, and a consumer's optimum sits where the budget constraint meets a tangency condition. This module tests whether the agent can solve small systems of linear equations, apart from any economic setting.
