Question

Can somebody help me out with this problem? You don't need to tell me the answer just help me work it out please.

Answer 1

Hey!

So first, you need to isolate the y variable:

sqrt 2y = 9 ==> subtract 3 from both sides.

Now, raise both sides of the equation to the power of 2 to eliminate the square root:

2y = 81

Solve for y by dividing both sides by 2.

Hope this helps :)
