What is the solution of the system? use elimination.

5x + 7y = 32
8x + 6y = 46
select one:
a. (5, 1)
b. (8, 5)
c. (7, 0)
d. (1, 5)

In the figure below, ∠dec ≅ ∠dce, ∠b ≅ ∠f, and segment df is congruent to segment bd. point c is the point of intersection between segment ag and segment bd, while point e is the point of intersection between segment ag and segment df. the figure shows a polygon comprised of three triangles, abc, dec, and gfe. prove δabc ≅ δgfe.
