Question

Solve for y 31=2y-5

Answer 1

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.

`(2y)/(2)=(36)/(2)`

Finally, simplify

`y=18`

And the answer is
`y=18`

I hope this helped!

Answer 2

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 (':
