Answer :

Sure! Let's break down the given problem step-by-step.

Given the equation [tex]\( 5x = 9 \)[/tex]:

1. Solving for [tex]\( x \)[/tex]:

To isolate [tex]\( x \)[/tex], divide both sides of the equation by 5:
[tex]\[ x = \frac{9}{5} \][/tex]

From this, we get:
[tex]\[ x = 1.8 \][/tex]

2. Interpretation and application of [tex]\( MCM \)[/tex]:

The meaning of [tex]\( MCM _{(5x = 9)} \)[/tex] might depend on specific context, however assuming it's asking us to find a solution in the general algebraic sense, we continue with [tex]\( x = 1.8 \)[/tex].

3. Dealing with subsequent expressions:

The problem statement offers a subtraction to perform:
[tex]\[ 36 - 48 \][/tex]

Performing the arithmetic operation:
[tex]\[ 36 - 48 = -12 \][/tex]

So, summarizing the steps:
- Solved [tex]\( 5x = 9 \)[/tex] to find [tex]\( x = 1.8 \)[/tex]
- Performed the subtraction [tex]\( 36 - 48 = -12 \)[/tex]

Thus, the detailed, step-by-step solution to the problem given the equation [tex]\( 5x = 9 \)[/tex] and the subsequent arithmetic operation is:

The result is [tex]\(-12\)[/tex].
