This method of solving a system of linear ...This is our new system of equations: c + b = 300c + 5b = 90 c + b = 300 c + 5 b = 90. Now we can easily divide the second equation by 5 and get the value for b b: b = 90/5 = 18 b = 90 / 5 = 18. If we substitute 18 for b b into the first equation we get: c + 18 = 30 c + 18 = 30. And solving for c c gives us c c =30−18=12.5.1 Linear equations About 4000 years ago the Babylonians knew how to solve a system of two linear equations in two unknowns (a 2 × 2 system). In their famous Nine Chapters of the Mathematical Art (c. 200 BC) the Chinese solved 3 ×3 systems by working solely with their (numerical) coefficients. These were prototypes of matrix methods, notOur quest is to find the “best description” of the solution set. In system (3), we don’t have to do any work to determine what the point is, the system (because technically it is a system of linear equations) is just each coordinate listed in order. If the solution set is a single point, this is the ideal description we’re after. 25) Write a system of equations with the solution (4, −3). Many answers.
