1) To solve the equation 0,6x - 5,4 = -0,8x + 5,8, first,

add 0,8x to both sides to get:

0,6x + 0,8x - 5,4 = 5,8

Simplify this to get:

1,4x - 5,4 = 5,8

Now, add 5,4 to both sides to get:

1,4x = 11,2

Finally, divide by 1,4 to solve for x:

x = 11,2 / 1,4 = 8

So, x = 8

2) To solve the equation 4,7 - 1,1x = 0,5x - 3,3, first,

add 1,1x to both sides to get:

4,7 = 1,1x + 0,5x - 3,3

Simplify this to get:

4,7 = 1,6x - 3,3

Now, add 3,3 to both sides to get:

8 = 1,6x

Finally, divide by 1,6 to solve for x:

x = 8 / 1,6 = 5

So, x = 5

3) To solve the equation 5,6x + 16 = 4,9x + 9, first,

subtract 4,9x from both sides to get:

5,6x - 4,9x + 16 = 9

Simplify this to get:

0,7x + 16 = 9

Now, subtract 16 from both sides to get:

0,7x = -7

Finally, divide by 0,7 to solve for x:

x = -7 / 0,7 = -10

So, x = -10
