\left(x+2\right)\times 2=3
Variable x cannot be equal to any of the values -2,1 since division by zero is not defined. Multiply both sides of the equation by \left(x-1\right)\left(x+2\right), the least common multiple of x-1,\left(x-1\right)\left(x+2\right).
2x+4=3
Use the distributive property to multiply x+2 by 2.
2x=3-4
Subtract 4 from both sides.
2x=-1
Subtract 4 from 3 to get -1.
x=\frac{-1}{2}
Divide both sides by 2.
x=-\frac{1}{2}
Fraction \frac{-1}{2} can be rewritten as -\frac{1}{2} by extracting the negative sign.
