Answer 1

$\qquad\qquad\huge\underline{{\sf Answer♪}}$

If the given triangles are congruent, then their corresponding sides are equal as well ~

So, let's use this condition

$\qquad \sf  \dashrightarrow \:2y + 5 = 3y + 2$

$\qquad \sf  \dashrightarrow \:3y - 2y = 5 - 2$

$\qquad \sf  \dashrightarrow \:y = 3$

and

$\qquad \sf  \dashrightarrow \:2x + 7 = 15$

$\qquad \sf  \dashrightarrow \:2x = 8$

$\qquad \sf  \dashrightarrow \:x = 4$
