SOLUTION:
Step 1:
In this question, we are given the following:
[tex]\text{3x + 4 = x + 8}[/tex]Step 2:
The details of the solution are as follows:
[tex]\begin{gathered} 3x\text{ + 4 = x + 8} \\ collect\text{ like terms, we have that:} \\ 3\text{ x - x = 8 - 4} \\ 2x\text{ = 4} \\ Divide\text{ both sides by 2, we have that:} \\ x\text{ =}\frac{4}{2} \\ \text{x = 2 \lparen OPTION B \rparen} \end{gathered}[/tex]CONCLUSION:
The final answer is:
[tex]x\text{ = 2 \lparen OPTION B \rparen}[/tex]
