First you had to add and subtracting by the numbers.
[tex]16-99=-83[/tex]
[tex]y-83=5y-7[/tex]
Then you add by eighty-three from both sides of equation form.
[tex]y-83+83=5y-7+83[/tex]
Simplify.
[tex]y=5y+76[/tex]
Next, you subtract by five-y from both sides of equation form.
[tex]y-5y=5y+76-5y[/tex]
Then simplify.
[tex]-4y=76[/tex]
You can also divide by negative four from both sides of equation form.
[tex]\frac{-4y}{-4}= \frac{76}{-4}[/tex]
Finally, simplify by equation.
[tex]\frac{-4y}{-4}=y[/tex]
[tex]\frac{76}{-4}=-19[/tex]
[tex]y=-19[/tex]
Final answer: [tex]\boxed{y=-19}[/tex]
Hope this helps!
And thank you for posting your question at here on brainly, and have a great day.
