Answer 1

0,7+0,3(x+2)=0,4(x-3)0,7+0,3x+0,6=0,4x-1,20,3x-0,4x=-0,7-0,6-1,2-0,1x=-2,5x=-2,5/(-0,1) x=25 

Answer 2

0,7+0,3(х+2)=0,4(х-3) 
0,7+0,3х+0,6=0,4х-1,2
0,3х-0,4х=-1,2-0,7-0,6
-0,1х=-2,5
х=-2,5/(-0,1)
х=25

Answer 3

To solve the equation 0.7 + 0.3(x + 2) = 0.4(x - 3), we will follow the steps below:

1. Distribute the terms on both sides of the equation: 0.7 + 0.3x + 0.6 = 0.4x - 1.2

2. Combine like terms: 0.3x + 1.3 = 0.4x - 1.2

3. Move all the terms with x to one side of the equation and the constant terms to the other side. We'll subtract 0.3x from both sides and add 1.2 to both sides: 0.3x - 0.4x = -1.2 - 1.3

   Simplifying the equation further: -0.1x = -2.5

4. Divide both sides of the equation by -0.1 to solve for x: x = (-2.5) / (-0.1)

   The negative sign cancels out, resulting in: x = 25

Therefore, the solution to the equation 0.7 + 0.3(x + 2) = 0.4(x - 3) is x = 25.
