1)

3,4x - 4 = 4,8 - x

First, let's simplify the equation by combining like terms:

3,4x + x = 4,8 + 4

4,4x = 8,8

Now, divide both sides by 4.4 to solve for x:

x = 8,8 / 4,4

x = 2

Therefore, the solution to the equation 3,4x - 4 = 4,8 - x is x = 2.

2)

2x + 7 = x + 5,5

First, let's simplify the equation by combining like terms:

2x - x = 5,5 - 7

x = -1,5

Therefore, the solution to the equation 2x + 7 = x + 5,5 is x = -1,5.
