1.2 - ( 0.8 + x ) = - 3.6
1) Clear the parentheses by distributing the - sign
1.2 - 0.8 - x = - 3.6
2) Combine like terms
0.4 - x = - 3.6
3) Subtract 0.4 from both sides
- x = - 4
4) Multiply both sides by - 1 to clear the minus sign in front of x
x = 4

Edit: did it wrong at the start, i'll start again.
+ 3.6 to both sides.
This makes 3.6 + 1.2 - 0.8 - X = 0 (multiply everything in the bracket by minus 1)
= 4- X = 0
X = 4

1.2 - (0.8 + x) = -3.6
(multiply out brackets)
1.2 - 0.8 - x = -3.6
(+1.2 to both sides)
- 0.8 - x = -4.8
(+0.8 to both sides)
-x = -4
x = 4
