Lets multiply the -1 with the first bracket and also -2 with the second bracket. Since they are negative numbers, when they will multiply with a positive number the result will be negative and when the multiply with a negative number the result will be positive.
-2x-3-2x+2=
Lets add the unknown values together and the numbers together.
-4x-1=
If we equal it with a 0 we will have this result.
-4x-1=0
-4x=1
Lets divide both sides with -4.
-4x/(-4) = 1/(-4)
x=1/(-4)
