Can someone help me with Pre-Algebra?

Question

2/3 y-4=2?

anyone explain&answer?

thanks

Answer 1

find the value for y

2/3y-4=2                   get y by itself--to do that you add 4 to each side

      +4 +4

                                that gets you 2/3y=6. divide each side by 2/3 to

                                get y by itself. 6 divided by 2/3 is 9. so y=9.

                                thats your answer

2/3y=6

y=9

Answer 2

2/3 y-4=2

2/3 y = 2 + 4 = 6

2y = 6(3) = 18

y = 18/2 = 9

Answer 3

2/3y - 4=2

you want to put why by itself by isolating it.

2/3y - 4= 2

       +4   +4                            This makes 2/3 y alone on

         ^     ^                           the other side of the equation            

         add 4        

2/3y=6                 u have to divide to get the answer to cancel out 2/3  

                          and get y alone... to do this multiply by the  reciprocal to BOTH SIDES.( 3/2  ) It will cancel 2/3 when u mulitply it.



                 (3/2) 2/3y=  6(3/2)    

                       y =  18/2, which when simplified is

                      y= 9
