Consider the following system of linear equations

12.6x + 5y = 14.6

19.5x+10.4y = 15.9.

What is the elementary row operation needed to make the first entry in row 2 equal to zero?

Question 4Answer

a.R2 = 19.5R1 + 12.6R2

b.R2 = 19.5R1 - 12.6R2

c.R2 = -5.6R1 + 8.9R2

d.R1 = R1 - R2

e.R1 = 19.5R1 + 12.6R2

f.R2 = R1 - R2
