12k + 1 = 8k - 2 what is the value of k?

12k+1= 8k- 2
12 times 8k +1=
96k+1= 97k

You first subtract 8k from both sides which equals 

4k+1= -2

-1 from both sides

4k= -3

divide both sides by 4

k= -3/4

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
