rearrange 3x+y =-5 to solve for y:
y = -3x-5
substitute -3x-5 for y into the second equation:
12x + 3y = 13
12x + 3(-3x-5) = 13
12x - 9x - 15 = 13
3x = 28
x = 28/3
y = -3x-5 = -33
solution: (28/3, -33)

Answer:
1.5 nautical miles
Step-by-step explanation:
See the attached diagram.
The submarine starts to dive at point A and diving along AB.
If the distance traveled underwater i.e. AB = 1.7 Nautical miles and C is the point directly above its current position at B.
Then Δ ABC is a right triangle having ∠ BAC = 28° {Given}
So, using trigonometry we can write
⇒ nautical miles.
Therefore, the surface distance that the submarine travels is 1.5 nautical miles. (Answer)
