The number of boys and girls in a class exists in the ratio 1:4 given that there are 8 boys in the class,calculate.the number of girls in the class and total number of students in the class

1. x = -3y - 6

2. x = (-3y - 3)/2

Step-by-step explanation:

To get x on its own, we have to add 3y to both sides. We have x = -3y - 6. For the next one, we also want to isolate the variable. So we subtract 3y and we end up with 2x = -3y - 3. Then we divide both sides by 2 and we have our answer. I hope this helps because I didn't really understand the question...
