-1/2=3/2k+3/2<br> explain how you got your answer
meriva

-1/2=3/2k+3/2


Rewrite the equation to have k on left side


3/2k+3/2=-1/2


Simplify 3/2k


3k/2+3/2=12


Move all terms not containing k to right side


3k/2=1/2-3/2


3k/2=-2


Multiply both sifmdes by 2


2(3k/2)=-2(2)


3k=-4


Divide both sides by 3 to get k alone


3k/3=-4/3


K= -4/3
