x= -41/2

12x-20=14x+21
12x-20+20=14x+21+20
12x=14x+41
12x-14x=14x+41-14x
-2x=41
-2x/-2=41/-2
x=-41/2

Distribute the four and seven to get
12x-20=14x+21
Then subtract the 12x and both side and get
-20=2x+21
The subtract 21 on both sides to get
-41=2x
Then divide both sides by 2 and get
X=-41/2
And as a decimal it is -20.5
