$\left[ 2,\infty \right)$
Solving the inequalities separately results to \begin{array}{l} -2x\le-4\\ x\ge2 ,\\\\\text{OR}\\\\ 5x-20\ge5\\ 5x\ge25\\ x\ge5 .\end{array} Using the conjuntion "or" the solution set is the combined solutions sets of both inequalities. Hence, the solution set is $\left[ 2,\infty \right)$.
