Question

Which answer choice below is a solution to this equation?3x + 4 = x + 8A. 5 B. 2C. -6D. -1

Answer 1

Step 1:

In this question, we are given the following:

`\text{3x + 4 = x + 8}`

Step 2:

The details of the solution are as follows:

`\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{ =}(4)/(2) \\ \text{x = 2 \lparen OPTION B \rparen} \end{gathered}`

CONCLUSION:

The final answer is:

`x\text{ = 2 \lparen OPTION B \rparen}`
