When you add -10 times the first row to the second you should get (-60)+(-9) = -60. You've written -51?

After i zero the second and third then im lost..:/ i cant zero anymore:( - November 27th 2012, 11:36 AMfkfRe: Linear equation
Den go to the second row, and divide by -9 to get new leading one. After that. Add a multiple of second row to third row to get zero below.
