9-а=4 как решить формула решение

Answer 1

9-а=4

а=9-4

а=5

Проверка:

9-5=4

Answer 2

To solve the equation 9 - a = 4, you need to isolate the variable "a" on one side of the equation. Here are the steps to do so:

Step 1: Move the constant term to the other side of the equation. To do this, add 4 to both sides of the equation:

9 - a + 4 = 4 + 4

Simplifying the equation:

13 - a = 8

Step 2: Isolate the variable "a." To do this, move the remaining constant term to the other side of the equation by subtracting 13 from both sides:

13 - a - 13 = 8 - 13

Simplifying the equation:

-a = -5

Step 3: Solve for "a." To isolate "a" completely, multiply both sides of the equation by -1 (since -a = -1 * a):

-1 * (-a) = -1 * (-5)

Simplifying the equation:

a = 5

So, the solution to the equation is a = 5.
