Answer 1

Ответ:

Пошаговое объяснение: (x+4)(y-5)=xy+4y-5x-20

(x-8)(6-y)=6x-48-xy+8y

Answer 2

(х+4)(у-5)=ху-5х+4у-20
(х-8)(6-у)=6х-ху-48+8у

Answer 3

To find the values of x and y that satisfy both equations, we can set them equal to each other and solve for x and y.

Equation 1: (x + 4)(y - 5) = (x - 8)(6 - y)

Let's first expand both sides of the equation:

Expand the left-hand side: xy - 5x + 4y - 20 = 6x - xy - 8y + 40

Now, let's group the x and y terms on one side of the equation:

2xy - 5x + 4y = 6x - 8y + 40 + 20 2xy - 5x + 4y = 6x - 8y + 60

Next, let's move all the x and y terms to one side:

2xy - 5x - 6x + 8y - 4y = 60

Simplify:

2xy - 11x + 4y = 60

Equation 2: (x - 8)(6 - y)

Let's expand this equation:

6x - xy - 8y + 48

Now, set this equation equal to the previous result:

2xy - 11x + 4y = 6x - xy - 8y + 60

Now, let's rearrange the equation and simplify:

2xy + xy = 6x - 11x + 4y + 8y + 60 - 48 3xy = -5x + 12y + 12

Now, we have a system of equations:

1. 2xy - 11x + 4y = 60
2. 3xy = -5x + 12y + 12

To proceed further, we'll need more information or another equation. The current system of equations is not sufficient to uniquely determine the values of x and y. If you have another equation or additional information, please provide it, and I'll be happy to help you solve for x and y.
