Question

Упростите выражения и найдите его значение: 1. х-41-14 при х=98 2. 11+х-17-у при х=16, при у=12. 3. х-21-43-68 при х=196 4. 13+х+71-у при х=14, при у=23 Помогите пожалуйста!!!!!!

Answer 1

1) x-41-14=x-27
x=98
98-27=71
2) 11+х-17-у= x-y-6
 при х=16, при у=12
16-12-6= - 2
3)  х-21-43-68=x-( - 132)
 при х=196
196 - ( -132)=328
4) 13+х+71-у= x-y+84
при х=14, при у=23
14 - 23 + 84= 75

Answer 2

Simplifying Expressions and Finding Their Values

1. To simplify the expression `х - 41 - 14` when `х = 98`, we substitute the value of `х` into the expression and perform the calculations:

`98 - 41 - 14 = 43 - 14 = 29`

Therefore, when `х = 98`, the value of the expression `х - 41 - 14` is 29.

2. To simplify the expression `11х - 17 - у` when `х = 16` and `у = 12`, we substitute the values of `х` and `у` into the expression and perform the calculations:

`11 * 16 - 17 - 12 = 176 - 17 - 12 = 147 - 12 = 135`

Therefore, when `х = 16` and `у = 12`, the value of the expression `11х - 17 - у` is 135.

3. To simplify the expression `х - 21 - 43 - 68` when `х = 196`, we substitute the value of `х` into the expression and perform the calculations:

`196 - 21 - 43 - 68 = 175 - 43 - 68 = 132 - 68 = 64`

Therefore, when `х = 196`, the value of the expression `х - 21 - 43 - 68` is 64.

4. To simplify the expression `13х + 71 - у` when `х = 14` and `у = 23`, we substitute the values of `х` and `у` into the expression and perform the calculations:

`13 * 14 + 71 - 23 = 182 + 71 - 23 = 253 - 23 = 230`

Therefore, when `х = 14` and `у = 23`, the value of the expression `13х + 71 - у` is 230.

I hope this helps! Let me know if you have any further questions.
