А:30=768+968(х+240)*3-360=540876+у+9869=78000Реши уравнение20баллов

Answer 1

A:30=768+968
a/30=1736
Ответ: a=52080

(x+240)*3-360=540
3x+720-360=540
3x+360=540
3x=540-360
3x=180
Ответ: x=60

876+y+9869=78000
10745+y=78000
y=78000-10745
y=78000-10745
Ответ: y=67255

Answer 2

To solve the equation, let's first simplify it step by step:

1. А:30 = 768 + 968(х + 240) * 3 - 360
2. 540876 + у + 9869 = 78000

Step 1: Start by distributing the multiplication: А:30 = 768 + 2904х + 2904*240 - 360

Simplify further: А:30 = 768 + 2904х + 697440 - 360 А:30 = 697848 + 2904х

Step 2: Now rewrite the equation using the simplified form of А:30: 697848 + 2904х = 540876 + у + 9869

Step 3: Subtract 540876 and 9869 from both sides to isolate the terms with у and х on one side: 697848 + 2904х - 540876 - 9869 = у

Simplify further: 697848 - 540876 + 2904х - 9869 = у 156972 + 2904х = у

Now we have the following system of equations:

1. 697848 + 2904х = А:30
2. 156972 + 2904х = у

We are asked to solve this system to find the values of у and х.

Unfortunately, there is a problem with the provided equation. The symbol "А" is used in a way that doesn't make sense mathematically. We can't treat it like a variable without knowing its value or relation to the other variables.

Could you please provide more information or clarify the equation to continue solving it and award the points accordingly?
