I covered up one of the numbers with my mouse as it is a typo in the equation.

Q. (Use Python/MATLAB/Mathematica for this] Solve the following system of equations for the variables ...IS 2.C +.7.12 - 3.5x3 + 7x4 - 53s = 2 -1.2.11 +2.7.02- 3.01 - 2.505 = -17 - 21 +22 - 13 - 14 + x = 5 2.9.1 +7.5.25 = 0 1.8.13 - 2.7x4-5.5.15 -11 Show that the calculated solution is indeed correct by substituting in each equation above and making sure that the left hand side equals the right hand side
