Answer:
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
