Answer 2

$y = 14 - x \\x {}^{2} + (14 - x) {}^{2} - 100 = 0 {}^{} \\ \\ x {}^{2} + 196 - 28x + x {}^{2} - 100 = 0 \\ 2x {}^{2} - 28x + 96 = 0| \div 2 \\ x {}^{2} - 14x + 48 = 0 \\ d = 196 - 4 \times 1 \times 48 = 4 \\ x1 = \frac{18}{2} = 9 \\ x2 = \frac{10}{2} = 5 \\ y1 = 14 - 9 = 5 \\ y2 = 14 - 5 = 9$
