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.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.A System of Linear Equations is when we have two or more linear equations working together.
