Question

2,7x - 2,8 = 4,2 – 4,3x​

Answer 1

Ответ:

$2.7x - 2.8 = 4.2 - 4.3x \\ 2.7x + 4.3x = 4.2 + 2.8 \\ 7x = 7 \\ x = 1$

Answer 2

To solve the equation 2.7x - 2.8 = 4.2 - 4.3x, you can follow these steps:

Step 1: Move the terms with x to one side of the equation and the constants to the other side. You can do this by adding 4.3x to both sides and adding 2.8 to both sides:

2.7x + 4.3x = 4.2 + 2.8

Step 2: Combine like terms on both sides of the equation:

(2.7x + 4.3x) = 7x (4.2 + 2.8) = 7.0

So, the equation becomes:

7x = 7.0

Step 3: Solve for x by dividing both sides by 7:

7x / 7 = 7.0 / 7

x = 1.0

Therefore, the solution to the equation 2.7x - 2.8 = 4.2 - 4.3x is x = 1.0.
