0,53x - 3,4=7,2

To solve the equation 0,53x - 3,4 = 7,2 in Russian, you need to isolate the variable x.

1. First, add 3,4 to both sides of the equation: 0,53x - 3,4 + 3,4 = 7,2 + 3,4 0,53x = 10,6

2. Next, divide by 0,53 to find the value of x: x = 10,6 / 0,53 x = 20

Therefore, the solution to the equation is x = 20.
