add two to both sides, so you get

now square both sides and continue. Check the solution when done, squaring often introduces erroneous solutions

stop making posts like these. it is seen as begging and bumping, which is against the rules. - Apr 20th 2008, 04:44 PMimbadatmath

if i square both sides i get y+4=25 then i subtrace 4 from both sides and i get y=21 is this correct?

well 21 plus 4 is 25 then the square root of 25 is 5 so 5 -2=3 so 21 is the correct answer?
