Hello there! In this situation you would divide both sides by 9 giving you: y² = 0.444~ Take the square root of both sides and the equation becomes y = √0.444
If you'd rather a fraction answer, then dividing both sides gives you y^2= 4/9. Taking the square root of both sides due to y being squared gives you y= +_ 2/3 ( with the minus under the plus to indicate plus OR minus)
