Answer 2

It seems like you've provided an equation that you'd like to solve for the variable "x". Let's solve it step by step:

Given equation:

(1,3 + 5/9x) × 0,4 = 7/9x - 1

First, let's simplify the equation:

1. Distribute 0.4 to both terms inside the parentheses on the left side:

   0.4 * 1.3 + 0.4 * (5/9x) = 7/9x - 1

   0.52 + (2/45)x = 7/9x - 1

2. Move all terms containing "x" to one side of the equation and constants to the other side:

   (2/45)x - 7/9x = -1 - 0.52

   (2/45 - 14/45)x = -1.52

   (-12/45)x = -1.52

   (-4/15)x = -1.52

3. Now, isolate "x" by dividing both sides of the equation by (-4/15):

   x = (-1.52) / (-4/15)

   x = (-1.52) * (-15/4)

   x = 5.7

So, the solution for the equation is x = 5.7.
