Matrix tool? From what? A graphing calculator? Or something like mathway?
its an arrangment of columns and rows such as
0 0 0|0
0 0 0|0
0 0 0|0
I'm well aware of what a matrix is. You're talking about some matrix tool. Any idea what that might be referring to?
Last operation should be R1 = R1+7/11(R2)
46/11 0 0 | -15 + 7/11*17
so 46/11x = -15 + (7/11)*17
x = -1
That is the correct solution
I think what they call a matrix tool is not a device or a program but the solution method i used above. They are not hard to solve but takes some time
thanks i really didnt know ho to solve a three row matrix
They are not hard to solve. If you want to find x just leave its coefficient alone(make othes 0) by adding and subtracting other rows from any row you chose. After finding something like:
a 0 0 | b
You can write it as ax + 0y + 0z = b
It is equal to ax = b
and x = b/a
In my solution you can see that second element of the first row became 0. Then i tried to make 3rd element 0. But if i add or subtract 2nd or 3rd row the second element would be different than 0. So i prepared the second row first by making the second elemnt of it 0. Then i maked the 3rd element of first row 0
