Question

Help ASAP! What does this exactly mean and how do I solve it?

Answer 1

1 , 4 , -14000 in the first three boxes

-2 , -5 , 200000 in the bottom three boxes

Explanation:

Recall that the values shown in the augmented matrix that you are given represent the coefficients used in the following equations:

`1\,x_1+0\,x_2-1\,x_3-4\,x_4=-14000\\and\\0\,x_1+1\,x_2+2\,x_3+5\,x_4=200000`

Therefore, you can solve for x1 in the first equation, and for x2 in the second one , and then complete the boxes that you are presented with, using the coefficients that accompany each variable, and the last box is for the constant value (pure number term). Then you need to first solve for the given variables, and then use the coefficients found to input their values in the boxes:

`x_1=1\,x_3+4\,x_4-14000\\and\\x_2=-2\,x_3-5\,x_4+200000`

So, please type in the first row of boxes, the numbers:

1 , 4 , -14000 (in this order) to complete the three boxes.

And in the second row of boxes:

-2 , -5 , 200000 (in this order)
