# Apply the given elementary transformation of the following matrix. A = [12-1013], 2C2 B = [102245], −3R1 Find the addition of the two new matrices. - Mathematics and Statistics

Sum

Apply the given elementary transformation of the following matrix.

A = [(1,2,-1),(0,1,3)], 2C2

B = [(1,0,2),(2,4,5)], −3R1

Find the addition of the two new matrices.

#### Solution

A = [(1,2,-1),(0,1,3)]

By 2C2, we get,

A ∼ [(1,4,-1),(0,2,3)]

B = [(1,0,2),(2,4,5)]

By −3R1, we get,

B ∼ [(-3,0,-6),(2,4,5)]

Now, addition of the two new matrices

= [(1,4,-1),(0,2,3)]+[(-3,0,-6),(2,4,5)]

= [(-2,4,-7),(2,6,8)]
