Y=4
the answer is y=4 because you had to subtract 8 from both sides.
30 students.....14 are boys...that means (30 - 14) = 16 are girls
if 2 boys are dropped......14 - 2 = 12 boys
and 2 girls are added......16 + 2 = 18 girls
fraction of the class that are boys is : 12/30 which reduces to 2/5 <==
The answer would be 361/4 added to each side of the formula
