Answer

No solution.

Work Step by Step

Using the properties of equality, the solution to the given equation, $ 3(x+4)=3(x-1) $, is \begin{array}{l} 3x+12=3x-3 \\\\ 3x-3x=-3-12 \\\\ 0=-15 \text{ (FALSE)} .\end{array} Since the solution above ended with a FALSE statement, then the given equation is a contradiction.
