we are given two system of equations
First equation is
we can write as
Second equation is
now, we can find augmented matrix
now, we can change it into reduced row echelon form
step-1: multiply the 1st row by -1/2
step-2: add -6 times the 1st row to the 2nd row
step-3:multiply the 2nd row by 1/2
step-4:add 1/2 times the 2nd row to the 1st row
so, we will get
