First solve the system

$$\begin{array}{rcrcr}4 x_1 & + & 959 x_{2} & = & 37 \\59 x_1 & + & 85 x_{2} & = & -4\end{array}$$

with Gaussian elimination with three significant digits of accuracy. Then solve the system again with three significant digits of accuracy, incorporating partial pivoting. To enter scientific notation, use x and ^. For example, type 2.12 x 10^(-3) to enter $2.12 \times 10^{-3}$. Note that you must enter all answers in scientific notation, even if the power of $10$ is zero.

Gaussian Elimination: $(x_1,x_2) = \bigg($ , $\bigg)$

Partial Pivoting: $(x_1,x_2) = \bigg($ , $\bigg)$
