Question

3|x| -|5+y| = если х = -3, у = -7

Answer 1

Ответ:

7

Пошаговое объяснение:

3|x| -|5+y| =3|-3| -|5+(-7)| =3·3-|5+(-7)|=3·3-2=7

Answer 2

To evaluate the expression 3|x| - |5+y| when x = -3 and y = -7, we substitute the given values into the expression:

3|x| - |5+y|

Substituting x = -3 and y = -7:

3|-3| - |5+(-7)|

Simplifying the absolute values:

3 * 3 - |5 - 7|

3 * 3 - |-2|

Multiplying and simplifying further:

9 - 2

The final result is:

7
