Fastest time to solve 10 simultaneous equations (set of 3)

On 20 October 2010, Turkish mathematician Selçuk Soner Akgül solved 10 sets of linear simultaneous equations (each set consisting of three equations in three unknown variables) – completing the task in 10 minutes 21.77 seconds, the fastest anyone has ever managed. He completed this incredible feat at the 9th Mathematics Symposium at Karadeniz Technical University, Turkey. A set of simultaneous equations is a group of mathematical formulae, equal in number to the number of unknown variables that they contain. So, for example, 2x + y = 4 and y – x =1 form a valid set of simultaneous equations, because there are two equations and two unknown variables, x and y. In this case, the equations have the unique solution x = 1, y = 2. The simultaneous equations solved by Selçuk Soner Akgül for his world record attempt were more complex than this – each set involving three equations in three unknown variables.
