Answer:
By using Carl Gauss's clever formula, (n / 2)(first number + last number) = sum, where n is the number of integers, we learned how to add consecutive numbers quickly. We now know that the sum of the pairs in consecutive numbers starting with the first and last numbers is equal.
Answer:
The equations that represent the situation are:
2y+x=5
5x-y=3
First divide by 4 to get x^2=9. Then take the square root of both sides. x=3 and x = -3.
