A:

Answer:x = 3y = 2Step-by-step explanation:When 2 triangles are congruent, they will have exact same 3 sides length and exact same 3 angles measure.So we can say:-2x + 6y = 6and-7x + 8y = -5Let's multiply first equation by 7 and 2nd equation by -2, to get:7 [-2x + 6y = 6] = -14x +42y = 42and-2 [-7x + 8y = -5] = 14x - 16y = 10Now adding these 2 new equations and solving for y:-14x +42y = 4214x - 16y = 10----------------------26y = 52y = 52/26y = 2Now we put y = 2 into 1st equation (or any other) and solve for x:-2x + 6y = 6-2x + 6(2) = 6-2x + 12 = 66 = 2xx = 6/2x = 3
