-3=2x
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by x.
2x=-3
Swap sides so that all variable terms are on the left hand side.
x=\frac{-3}{2}
Divide both sides by 2.
x=-\frac{3}{2}
Fraction \frac{-3}{2} can be rewritten as -\frac{3}{2} by extracting the negative sign.
