Steps for Solving Systems of Linear Equations in Three Variables 1. Select two of the equations and eliminate one of the variables form one of the equations. Select 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.When solving a system of two equations of two unknowns, if you get an equation like 0 = 1, then there can be no solution. If, on the other hand, you get an equation like 0 = 0, then the system is (probably) dependent. Example 1: Consider the system 2x + y = 5 x – y = 1 . The solution is x = 2, y = 1.
