2/x+3 = o

solve for x.
Is this where I go: 2= 0
x+3=0?

For the equation

(2/x) + 3 = 0
tells us that x cannot be zero, so we multiply by x to get
2*x/x + 3x = 0*x
3x+2 = 0
x = -2/3

If the equation is meant to be:
2/(x+3) = 0,
then there is no solution, because only in the lim x->∞ that the left hand side can approach zero.
