Answer 2

Пошаговое объяснение:

а - 45 = 389 - 245,

а - 45 = 144,

а = 144 + 45,

а = 189

Answer 3

To solve the equation, you want to find the value of variable "А" that makes both sides of the equation equal.

The equation is: А - 45 = 389 - 245

Let's solve it step by step:

1. Subtract 45 from both sides to isolate "А" on the left side of the equation: А = (389 - 245) + 45

2. Perform the subtraction inside the parentheses: А = 144 + 45

3. Add 144 and 45 together to get the value of "А": А = 189

So, the solution to the equation is А = 189.
