967. Найдите значение выражения |x + y| + х, если: 1) x = 2,8, y = -3,9; 2) x = -4,5, y = 7,2; 3) x = -2,3, y = -6,2; 4) x = -\frac{1}{15}, y = 2\frac{7}{18}

\[ |x + y| + x = |2.8 + (-3.9)| + 2.8 = |-1.1| + 2.8 = 1.1 + 2.8 = 3.9 \]

Ответ: 3.9

\[ |x + y| + x = |-4.5 + 7.2| + (-4.5) = |2.7| - 4.5 = 2.7 - 4.5 = -1.8 \]

Ответ: -1.8

\[ |x + y| + x = |-2.3 + (-6.2)| + (-2.3) = |-8.5| - 2.3 = 8.5 - 2.3 = 6.2 \]

Ответ: 6.2

\[ x = -\frac{1}{15}, y = 2\frac{7}{18} = \frac{43}{18} \]

\[ |x + y| + x = |-\frac{1}{15} + \frac{43}{18}| - \frac{1}{15} = |-\frac{6}{90} + \frac{215}{90}| - \frac{1}{15} = |\frac{209}{90}| - \frac{1}{15} = \frac{209}{90} - \frac{6}{90} = \frac{203}{90} = 2\frac{23}{90} \]

Ответ: 2\frac{23}{90}
