Answer 2

Answer:

Solving using Matrix method.

Step-by-step explanation:

Given that:

$\left[\begin{array}{cccc}9&38&47&4\\6&35&42&x\\12&21&23&27\end{array}\right]$

Now we are going subtract the value of the second row from the first row,

We get ,

$\left[\begin{array}{cccc}9&38&47&4\\3&3&5&4-x\\12&21&23&27\end{array}\right]$

Now, let the sum of the first three numbers that is present, will be equal to the sum of the digits.

The first columns will be present in the third row as follows:

Therefore, it is ,

1+2 =3

2+1=3

2+3= 5

Now we are going to interchange the patterns, we get,

2+7 = 4-x

Substituting we get,

9 = 4-x

X = 4-9 =-5

Here, 5 is minus value.

Therefore, the missing numbers present in the cells will be -5.
