Solve for X: 2 x 2 matrices.

Hello everyone,

I am here asking for maths help, the question I have difficult with is **question 2** , in my exam practice sheet. Here is the following:

Requirement:

**Solve for X:**

We know we need to use this method , which are two types:

**Type 1: AX** = **B** and **Type 2: XA** = **B**

But the issue is we must first do operations that will set it up to these two forms.

We know that we must remove the fraction because Matrices cant divided. I would assume we would times both sides by A to remove the fraction. But the problem is getting those two forms. With these operations.

Here is my working out: But i don't believe they're correct.

So my problem is I cant get **AX** = **B** or **XA** = **B**. So I can solve for X, If you want anymore details please tell me and I hope posted this in the correct section as well , I apologize if I didn't.

Kindest Regards,
