Final answer:

The solutions to the system of equations are (3, -14) and (-3, 16). This is obtained by expressing y from one equation, substituting it into another, and solving for x and y.

Step-by-step explanation:

The student asked for the solution to a system of equations:

  • 10 + y = 5x + x²
  • 5x + y = 1

To solve the system, we can start by expressing y from the second equation:

  • y = 1 - 5x

Substitute this expression for y into the first equation:

  • 10 + (1 - 5x) = 5x + x²

Now, we combine like terms and set the equation to zero to find the values of x:

  • x² + 5x - 5x + 1 - 10 = 0
  • x² - 9 = 0

Solving for x:

  1. x = 3
  2. x = -3

Substitute x back into y = 1 - 5x to find corresponding y values:

  1. For x = 3, y = 1 - 5(3) = -14
  2. For x = -3, y = 1 - 5(-3) = 16

Therefore, the solutions are (3, -14) and (-3, 16).
