Question

Find x such that the matrix is singular. A = 3 x −6 −4 x =

Answer 1

The value of x in matrix is 2.

According to the statement

we have a singular matrix A in the form of

$\left[\begin{array}{cc}3&x&\\-6&-4&\\&\end{array}\right]$

And we have to find the value of x then

Matrix, a set of numbers arranged in rows and columns so as to form a rectangular array. The numbers are called the elements, or entries, of the matrix.

Now we find the value of x by property of matrix then

Take both values equal to each other after multiplying

3 (-4) = x(-6)

Now solve the values

-12 = -6x

6x = 12

x = 2

Here in the matrix the value of x is 2.

So, The value of x in matrix is 2.
