It's a simple linear equation in 'y'. There is only one number that 'y' can be
that will make the equation a true statement. That number is called the
'solution' to the equation. Here's one way to find it:
You said that <u> 2 = y/5 - 8</u>
Add 8 to each side: 10 = y/5
Multiply each side by 5: <em> 50 = y</em>
Zero is equal to its negative
