You need to determine whether the triangles are congruent by ASA, SSS, SAS, AAS or HL. Then you can say that the triangles are congruent; after that, you need to go back to what the were asking you to prove, for example, if they were asking you to confirm that AC and GD were congruent, state that they are congruent and then put CPCTC as a reason. Am I making sense?

Step-by-step explanation:
x = 2 , y = 7
ans, y = 11 - 2x and 4x - 3y = -13
→ 7 = 11 - 2(2) → 7 = 11 - 4 → 7 = 7
→ 4(2) - 3(7) = -13 → 8 - 21 = -13 → -13 = -13
x = 5 , y = 2
→ 2x + y = 12 and x = 9 - 2y
as, 2(5) + 2 = 12 → 10 + 2 = 12 → 12 = 12
x = 9 - 2y → 5 = 9 - 2(4) → 5 = 9 - 4 → 5 = 5
x = 3 , y = 5
ans. 2x + y = 11 , x - 2y = -7
2(3) + 5 = 11 → 6 + 5 = 11 → 11 = 11
3 - 2(5) = 7 → 3 - 10 = 7 → 7 = 7
x = 7 , y = 3
ans. x + 3y = 16 and 2x - y = 11
7 + 3(3) = 16 → 7 + 9 = 16 → 16 = 16
2(7) - 3 = 11 → 14 - 3 = 11 → 11 = 11

Answer:
Step-by-step explanation:
99x - 44y = -605
-99x + 63y = 738
19y = 133
y = 7
-9x + 28 = 55
-9x = 27
x = -3
(-3, 7)
