Solve the Linear Equation: x + 8 + 3x - 4 = 0

To solve the linear equation $x + 8 + 3x - 4 = 0$, follow these steps:

• Step 1: Combine like terms.
  Combine the terms involving $x$, specifically $x + 3x = 4x$.
  Combine the constant terms, specifically $8 - 4 = 4$.
  The equation becomes $4x + 4 = 0$.
• Step 2: Isolate the variable $x$.
  Subtract 4 from both sides to get $4x = -4$.
• Step 3: Solve for $x$.
  Divide both sides by 4 to solve for $x$, resulting in $x = -1$.

Therefore, the solution to the equation is $x = -1$.
