Question

3,2-5а=-1,8а+4 пожалуйста чему равна а и как её найти

Answer 1

3,2-5а=-1,8а+4
-5а+1,8а=4-3,2
-3,2а=0,8
а=0,8:(-3,2)
а=-0,25

Answer 2

Тут просто переносишь числа в в одну сторону, буквы в другую:
-5а+1.8а=4-3.2
-3.2а=0.8
а=0.8/(-3.2)
а=-0.25

Answer 3

Solving the Equation 3.2 - 5a = -1.8a + 4

To solve the equation 3.2 - 5a = -1.8a + 4 and find the value of 'a', we can follow these steps:

1. Combine Like Terms: Combine the terms with 'a' on one side of the equation and the constant terms on the other side. 2. Isolate the Variable: Get 'a' by itself on one side of the equation. 3. Solve for 'a': Calculate the value of 'a' based on the simplified equation.

Let's proceed with these steps.

Combine Like Terms

First, let's combine the terms with 'a' on one side of the equation and the constant terms on the other side:

3.2 - 5a = -1.8a + 4

To combine like terms, we can add 1.8a to both sides of the equation:

3.2 + 1.8a - 5a = 4

Isolate the Variable

Next, let's simplify the equation:

3.2 - 3.2a = 4

Solve for 'a'

Now, let's solve for 'a':

3.2 - 3.2a = 4 -3.2a = 4 - 3.2 -3.2a = 0.8 a = 0.8 / -3.2 a = -0.25

The value of 'a' is -0.25.

By following these steps, we have found the value of 'a' in the given equation.
