31=2y-5

Add 5 on both -5+5 which cancels out and 31+5 which is 36 and then divide 36 by 2 which equals to 18.

So y=18 hope this helped (':

Hey!

31=2y-5

First, this problem should be switch sides.

2y-5=31

Secondly, add 5 from both sides of equation.

2y-5+5=31+5

Then, simplify

2y=36

In fact, you had to divide 2 from both sides of equation.

\frac{2y}{2}=\frac{36}{2}

Finally, simplify

y=18

And the answer is y=18

I hope this helped!

Thank you for posting your question.
