     In this case, we get a strengthened version of the translation of the Wakamatsu lemma to the exact context, and also prove that subcategories which are ${\displaystyle {\mathcal {E}}}$-resolving and epimorphic precovering with kernels in their right ${\displaystyle {\mathcal {E}}}$-orthogonal class and subcategories which are ${\displaystyle {\mathcal {E}}}$-coresolving and monomorphic preenveloping with cokernels in their left ${\displaystyle {\mathcal {E}}}$-orthogonal class are determined by each other.
