/**
 * Solves a system of linear equations using Gaussian elimination
 * @param {number[][]} coefficients Matrix of coefficients
 * @param {number[]} constants Vector of constants
 * @returns {number[]} Solution vector
 * @example
 * // Solves the system:
 * // x + y = 4
 * // x + 2y = 10
 * solveEquation([
 *   [1, 1],
 *   [1, 2]
 * ], [4, 10]); // returns [-2, 6]
 * @description
 * Uses Gaussian elimination with partial pivoting to solve a system of linear equations.
 * The solution is rounded to 1 decimal place.
