Question

А/30=768+987 (x+240)*3-360=540 876+y+9869=78000

Answer 1

Пошаговое объяснение:

а/30=768+987

а/30=1755

а=1755*30

а=52650

(x+240)*3-360=540

(x+240)*3=540+360

x+240=900/3

x+240=300

x=300-240

x=60

876+y+9869=78000

876+у+9869=78000

876+у=78000-9869

876+у=68131

у=68131-876

у=67255

Answer 2

To solve the given equations, we'll take them one by one:

1. A/30 = 768 + 987 To solve for A, we need to isolate A on one side of the equation. We can do this by multiplying both sides of the equation by 30: A = 30 * (768 + 987) A = 30 * 1755 A = 52650

So, the value of A is 52650.

2. (x + 240) * 3 - 360 = 540 Let's solve for x in this equation: First, distribute the 3 on the left side of the equation: 3x + 720 - 360 = 540 Next, combine like terms: 3x + 360 = 540 Now, isolate 3x by subtracting 360 from both sides: 3x = 540 - 360 3x = 180 Finally, solve for x by dividing both sides by 3: x = 180 / 3 x = 60

So, the value of x is 60.

3. 876 + y + 9869 = 78000 To solve for y, we need to isolate y on one side of the equation. Let's first combine the constants on the left side: 876 + y + 9869 = 78000 Add the numbers on the left side: 10745 + y = 78000 Now, isolate y by subtracting 10745 from both sides: y = 78000 - 10745 y = 67255

So, the value of y is 67255.

To summarize: A = 52650 x = 60 y = 67255
