Question

√2y+3=11 what's the value of y

Answer 1

Raysho, this is easier than it seems, I promise. Let's do it!

 

First, we have to move the 3 to the right side.  Subtracting 3 from both sides, we get √2y = 8

 

Now, the way to get rid of a square root is to square it.  (√8)² = √8 x √8 = √64 = 8, for example.

 

So, (√2y)² = 8²

 

2y = 64

 

Now, we divide both sides by 2 and get y = 32

 

Let's check.  √2(32) + 3 = 11

 

√64 + 3 = 11

 

8 + 3 = 11

 

11 = 11. Check!

 

Hope this helps!
