Answer 1

[4 -11 1 7 l -17]

[0 1 -1 -7 l 0]

[3 0 -2 2 l 12]

[4 1 5 3 l 7]

Explanation:

This is Finite Math, I got this hehe :)

To find the answer, first you need to understand what R means.

It stands for "row". So R1 means "Row 1".

So: -3R1 + R3 means that you need to multiply -3 by all of the numbers in row 1 and then add all of the numbers in row 3

[0 3 1 -1 l 6]

[0 1 -1 -7 l 0]

[3 0 -2 2 l 12]

[4 1 5 3 l 7]

Then use ^^THAT^^ and apply the next set of instructions.

-4R1 + R4 means that you multiply -4 by all of the numbers in row 1 and then add all of the numbers in row 4:

[4 -11 1 7 l -17]

[0 1 -1 -7 l 0]

[3 0 -2 2 l 12]

[4 1 5 3 l 7]
