Question

7 клас 3a(x+y)+x+y= 2m(m-n)-n+m= 7d(a-c)+ma-mc=

Answer 1

Ответ:

3а(x+y)+x+y=(x+y)×(3a+1)

2m(m-n)-n+m=(m-n)×(2m+1)

7d(a-c)+ma-mc=7ad-7cd+am-cm

Answer 2

It seems like you've provided a system of equations with multiple variables and expressions. Let me break it down and analyze the equations separately.

1. $3a(x+y) + x + y = 0$

2. $2m(m-n) - n + m = 7$

3. $7d(a-c) + ma - mc = 0$

To solve this system of equations, you would typically need as many equations as there are variables. In this case, you have three equations and three variables ($a$, $m$, and $d$), so theoretically, you can solve for these variables. However, the expressions involving $x$, $y$, and $n$ are not connected to the other equations. If you have additional information or context about how these variables are related, please provide that information so I can assist you further.
