To solve the equation
\[ (19 + 2x) - (5x - 11) = 25, \]
we first simplify the left side of the equation.
- Distribute the negative sign through the second parentheses:
\[ (19 + 2x) - 5x + 11 = 25. \]
- Combine like terms on the left side:
\[ 19 + 11 + 2x - 5x = 25. \]
This simplifies to:
\[ 30 - 3x = 25. \]
- Now, isolate the variable \(x\). Subtract 30 from both sides:
\[ -3x = 25 - 30, \]
which simplifies to:
\[ -3x = -5. \]
- Divide both sides by -3:
\[ x = \frac{-5}{-3} = \frac{5}{3}. \]
Thus, the solution is
\[ x = \frac{5}{3}. \]
