Solving Systems of 3x3 Linear Equations - Elimination
hanlonmath.comso z = –3. Now we substitute y = 5 and z = –3 into one of the original equations to find the value of x. 2x + y + 2z = 1 2x + 5 + 2(–3) = 1 2x – 1 = 1 2x = 2 x = 1. Our solution is an ordered triple (1, 5, –3). Those are values of the variables that make all three equations true. Let’s take a look at another 3x3 system of linear ...
