x+2-3x-3=2
Use the distributive property to multiply -3 by x+1.
-2x+2-3=2
Combine x and -3x to get -2x.
-2x-1=2
Subtract 3 from 2 to get -1.
-2x=2+1
Add 1 to both sides.
-2x=3
Add 2 and 1 to get 3.
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.
