x+3=-2x
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by x.
x+3+2x=0
Add 2x to both sides.
3x+3=0
Combine x and 2x to get 3x.
3x=-3
Subtract 3 from both sides. Anything subtracted from zero gives its negation.
x=\frac{-3}{3}
Divide both sides by 3.
x=-1
Divide -3 by 3 to get -1.
