A product means multiplication, so...
(x * -2) +8 = -4
-2x + 8 = -4
To isolate the x, we have a couple of different ways, but the easier for now would be to start off by moving the 8 to the other side via subtracting both sides by 8:
-2x + 8 - 8 = -4 - 8
-2x = -12
Next, we divide both sides by -2
-2x / -2 = -12 / -2
x = 6
