Question

20×а=568+432. 963-х=900-579​

Answer 1

20 х а=568+432

20а=1000

а=1000:20

а=50

963-х=900-579

963-х=321

х=963-321

х=642

Answer 2

Ответ:

20*a=568+432

20*a=1000

a=1000:20

a=50

Ответ:a=50.

963-х=900-579

963-х=321

х=963-321

х=642

Ответ:х=642

Answer 3

Let's solve these equations step by step:

1. $20a = 568 + 432$

First, let's add the numbers on the right side: $568 + 432 = 1000$

Now, let's isolate $a$ by dividing both sides by 20: $a = \frac{1000}{20} = 50$

So, $a = 50$.

2. $963 - x = 900 - 579$

First, let's perform the subtraction on the right side: $900 - 579 = 321$

Now, let's isolate $x$ by subtracting 321 from both sides: $963 - 321 = x$ $x = 642$

So, $x = 642$.
