WebWe'll say the coefficient on the x3 term there is 0. And then we have 1, minus 1, and 6. ... This one got completely zeroed out. I was able to reduce this system of equations to this system of equations. The variables that you associate with your pivot entries, we call these pivot variables. x1 and x3 are pivot variables. WebConsider a normal equation in x such as: 3x = 6. To solve this equation you simply take the 3 in front of x and put it, dividing, below the 6 on the right side of the equal sign. x = 6 3 = 3−1 ⋅ 6 = 2. at this point you can "read" the solution as: x = 2. With a system of n equations in n unknowns you do basically the same, the only ...
