Divide everything by 4 getting:
7y=3x+21
then get all of the variables on one side by subtracting 3x:
7y-3x=21
Lets assume the whole pie is 1, that is all fractions added together have to sum 1.
If Victor eats 1/6 out of 5/6, then the rest is 4/6 of the pie, that is the subtraction of those fractions.
Seven pizzas: 7 pizzas
Shared between 3 friends: 7 pizzas / 3 friends
Simplify the fraction:
7 / 3
(3 goes into 7 twice, 7 - 6 = 1)
2 1/3
The fraction of pizza that each friend gets is 2 1/3.
Hope this helps!! :)
