√y-13-4=6
Solve for y, where y is a real number.

You can put this solution on YOUR website!

sqrt%28y%29-13-4=6 ...first add -13 and -4 (recall, you add them as positive numbers just their sum has negative sign)
sqrt%28y%29-17=6 ...now move -17 to the right (recall, it will change a sign and become positive)
sqrt%28y%29=6%2B17
sqrt%28y%29=23 ...now raise both sides to a power of two
%28sqrt%28y%29%29%5E2=23%5E2 ...cancel power of two and sqrt
y=23%5E2
y=529
