What is the value of the element in row 1, column 1 of matrix c?

Option A is correct.

Step-by-step explanation:

We given with

We have to find Element in row 1 and column 1 of Matrix C.

Matrix C is Matrix X.

So, we have

So first we find inverse of first matrix,

Inverse of matrix A is given by

let,

then,

|A| = 4 × 1 - 0 × y = 4

So,

Element at row 1 and column 1 of matrix is

Therefore, Option A is correct.

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10

2

x=5
