Question

(16x-27y-20)² +(5x+18y-41,5)² =0помогите решить пожалуйста!!! ( я в 7 классе)

Answer 1

(16x-27y-20)²=0
(5x+18y-41,5)²=0
16x-27y-20=0
 5x+18y-41,5=0
16x-27y=20         *2  32x-54y=40
 5x+18y=41,5      *3  15x+54y=124,5
                                   47x=164,5 x=3,5 y=4/3
                                  

Answer 2

Solving the Equation (16x-27y-20)² + (5x+18y-41.5)² = 0

To solve the given equation, we can use the method of completing the square to simplify and solve for the variables x and y.

First, let's expand the given equation and then proceed with the steps to solve it.

Expanding the equation: (16x-27y-20)² + (5x+18y-41.5)² = 0

Expanding the squares: (16x-27y-20)(16x-27y-20) + (5x+18y-41.5)(5x+18y-41.5) = 0

Expanding further: (16x-27y-20)(16x-27y-20) = - (5x+18y-41.5)(5x+18y-41.5)

Now, let's proceed with the steps to solve the equation.

Steps to Solve the Equation:

1. Expand and Simplify: - Expand and simplify the equation by multiplying the terms.
