-3(y - 1)  =  9

                          First let's solve this equation for  y . Divide both sides by  -3 .

y - 1  =  9 / -3

 

y - 1  =  -3

                          Add  1  to both sides of the equation.

y  =  -3 + 1

 

y  =  -2

 

Now that we know  y  =  -2  ,   we can find the value of  \(\frac12\)y .

 

\(\frac12\)y  =  \(\frac12\)(-2)

 

\(\frac12\)y  =  -1
