Expert Solution

Step 1

Given system is

$A x = B Here, A = [\begin{matrix} 1 & \frac{1}{2} & \frac{1}{3} & \frac{1}{4} \\ \frac{1}{2} & \frac{1}{3} & \frac{1}{4} & \frac{1}{5} \\ \frac{1}{3} & \frac{1}{4} & \frac{1}{5} & \frac{1}{6} \\ \frac{1}{4} & \frac{1}{5} & \frac{1}{6} & \frac{1}{7} \end{matrix}], B = [\begin{matrix} \frac{25}{12} \\ \frac{77}{60} \\ \frac{57}{60} \\ \frac{319}{420} \end{matrix}]$
