are the following triangles congruent ? if so state the congruence the relarion ship

5x-y = 16

-3x + y = 6

(3x+1)(x-1)=3x(x-2)

3+x-6=20 find x

1. Reduce matrix into normal form and find rank

A = [2 1 -3 6

3 -3 1 2

1 1 1 2]

Reduce the matrix to Normal form and find it's Rank

1 2 -1 3

4 1 2 1

3 -1 1 2

1 2 0 1
