Question

7х-3х|у-7|при х=-7у=7 помогите решить, пожалуйста..

Answer 1

Ответ:

7*(-7)-3*(-7)|7-7|= -49 +21*0=-49

Answer 2

Solving the Equation 7x - 3x | y - 7 | When x = -7 and y = 7

To solve the equation 7x - 3x | y - 7 | when x = -7 and y = 7, we can substitute the given values of x and y into the equation and then simplify the expression.

Substituting x = -7 and y = 7 into the equation: 7(-7) - 3(-7) | 7 - 7 |

Simplifying the expression: -49 + 21 | 0 |

Now, we can simplify further: -49 + 21 = -28 | 0 | = 0

So, the final result is: -28

Therefore, when x = -7 and y = 7, the value of the expression 7x - 3x | y - 7 | is -28.
