You can put this solution on YOUR website!
y + 22/y = -13
multiply both sides by y
y%5E2+%2B+22+=+-13+%2A+y
add 13 * y to both sides
y%5E2+%2B+13%2Ay+%2B+22+=+0
factor
%28y+%2B+2%29%28y+%2B+11%29+=+0
y = -2
y = -11
you can check these answers by plugging back into
the original equation
%28-2%29+%2B+22%2F%28-2%29+=+-13
-2+-11+=+-13
OK
-11+%2B+22%2F%28-11%29+=-13
-11+-+2+=+-13
OK
