Answer:
y=17.98 (the answer should have a decimal point.)
Step-by-step explanation:
Isolate the term of y from one side of the equation.
Add by 9.2 from both sides of an equation.
[tex]\sf{y-9.2+9.2=8.78+9.2}[/tex]
Solve.
Add.
8.78+9.2=17.98
[tex]\large\boxed{y=17.98}[/tex]
Therefore, the correct answer is y=17.98.
