Question

A - 69 = 12 + 925 + x +43 + 245 - x = 100 - 60​

Answer 1

Ответ:

$a - 69 = 12 + 9 \\ 12 + 9 = 21 \\ a - 69 = 21 \\ a = 69 + 21 \\ a = 90 \\ 90 - 69 = 21$

$25 + x = 43 + 2 \\ 43 + 2 = 45 \\ 25 + x = 45 \\ x = 45 - 25 \\ x = 20 \\ 25 + 20 = 45$

$45 - x = 100 - 60 \\ 100 - 60 = 40 \\ 45 - x = 40 \\ x = 45 - 40 \\ x = 5 \\ 45 - 5 = 40$

Answer 2

Let's solve the equation step by step:

A - 69 = 12 + 925 + x + 43 + 245 - x = 100 - 60

First, simplify the equation:

A - 69 = (12 + 925 + x + 43 + 245 - x) = (100 - 60)

Now, let's simplify each side separately:

1. Simplify the left side:

A - 69

2. Simplify the right side:

(12 + 925 + x + 43 + 245 - x) = (12 + 925 + 43 + 245) - (x - x) = (12 + 925 + 43 + 245) - 0 = 1225

3. Simplify the right side further:

(100 - 60) = 40

Now, we have:

A - 69 = 1225

To solve for A, add 69 to both sides of the equation to isolate A:

A - 69 + 69 = 1225 + 69

A = 1294

So, the value of A is 1294.
