How many solutions does the following equations have?

one solution.: -6.5

Step-by-step explanation:

First you start with the side with parenthisis. So you multiply 7xY= 7y and then you multiply 7x3= 21 so you get 7y + 21 = 5y + 8

Second you subtract 8 from both sides.

7y + 21 = 5y +8

      -8  =       -8

wich leaves you with 7y + 13 = 5y

Next you want to subtract 7y from 5y because you cant have a variable on both sides.  7y + 13 = 5y

                   -7y + 13 = -7y which will leave you with 13= -2y

Now you divide each number by -2 to get "y" by itself.

13/-2 = -6.5 = y
