Short Answer

Expert verified

The solution of the given equation is $x = 1$ .

Step by step solution

Step 1. Given information.

The given equation is:

$3 x + 4 = 8 - x$

Step 2. Solve the equation.

First, isolate the variable terms to solve for $x$ .

$\begin{array}{rcl} 3 x + 4 & = & 8 - x \\ 3 x + x & = & 8 - 4 \\ 4 x & = & 4 \\ x & = & \frac{4}{4} \\ x & = & 1 \end{array}$

Step 3. Conclusion.

The solution of the given equation is $x = 1$ .
