Simplifying
-1(-4) = x
Multiply -1 * -4
4 = x
Solving
4 = x
Move all terms containing x to the left, all other terms to the right.
Add '-1x' to each side of the equation.
4 + -1x = x + -1x
Combine like terms: x + -1x = 0
4 + -1x = 0
Add '-4' to each side of the equation.
4 + -4 + -1x = 0 + -4
Combine like terms: 4 + -4 = 0
0 + -1x = 0 + -4
-1x = 0 + -4
Combine like terms: 0 + -4 = -4
-1x = -4
Divide each side by '-1'.
x = 4
Simplifying
x = 4

You have a minus minus. That always means positive. In fact, you can remember the final sign this way.
An even number of positives in front of a variable or constant means positive, while an odd number indicates negative.
