Solve the equation and simplify your answer.

[tex]\[
\begin{aligned}

x & = \frac{[?]}{n}
\end{aligned}
\][/tex]

(Note: Ensure that the final answer, [tex]\(\frac{[?]}{n}\)[/tex], is correctly simplified.)



Answer :

Sure! Let's solve the given equation step by step.

The given equation is:

[tex]\[ 3x + 4(x + 1) = x + 2(x + 3) \][/tex]

Step 1: Distribute the constants inside the parentheses.

On the left side of the equation:
[tex]\[ 3x + 4(x + 1) = 3x + 4x + 4 = 7x + 4 \][/tex]

On the right side of the equation:
[tex]\[ x + 2(x + 3) = x + 2x + 6 = 3x + 6 \][/tex]

So the equation now is:
[tex]\[ 7x + 4 = 3x + 6 \][/tex]

Step 2: Isolate the variable [tex]\(x\)[/tex].

First, subtract [tex]\(3x\)[/tex] from both sides:
[tex]\[ 7x + 4 - 3x = 3x + 6 - 3x \][/tex]
This simplifies to:
[tex]\[ 4x + 4 = 6 \][/tex]

Next, subtract 4 from both sides:
[tex]\[ 4x + 4 - 4 = 6 - 4 \][/tex]
This simplifies to:
[tex]\[ 4x = 2 \][/tex]

Step 3: Solve for [tex]\(x\)[/tex] by dividing both sides by 4:
[tex]\[ x = \frac{2}{4} \][/tex]
[tex]\[ x = \frac{1}{2} \][/tex]

Therefore, [tex]\(x\)[/tex] can be simplified and expressed as:
[tex]\[ x = \frac{1}{2} \][/tex]

So, the numerator and denominator are 1 and 2, respectively. Hence, the value of [tex]\(x\)[/tex] is [tex]\( \frac{1}{2} \)[/tex].
