Question

X-7y-|-6-5y| при x=-11,y=13

Answer 1

-11-91-|-6-65|= -102-|-71|= -102-71= -173

Answer 2

To evaluate the expression X-7y-|-6-5y| at x=-11 and y=13, we substitute the values of x and y into the expression and perform the calculations step-by-step:

X = -11 y = 13

Now, let's plug these values into the expression:

X-7y-|-6-5y|

-11 - 7(13) - | -6 - 5(13) |

Now, evaluate the inner expression inside the absolute value:

-6 - 5(13) = -6 - 65 = -71

Next, calculate the absolute value of -71:

|-71| = 71

Now, the expression becomes:

-11 - 7(13) - 71

Now, perform the multiplication:

-11 - 91 - 71

Finally, perform the additions:

-11 - 91 - 71 = -102 - 71 = -173

So, when x = -11 and y = 13, the expression X-7y-|-6-5y| evaluates to -173.
