27-2x=20
Swap sides so that all variable terms are on the left hand side.
-2x=20-27
Subtract 27 from both sides.
-2x=-7
Subtract 27 from 20 to get -7.
x=\frac{-7}{-2}
Divide both sides by -2.
x=\frac{7}{2}
Fraction \frac{-7}{-2} can be simplified to \frac{7}{2} by removing the negative sign from both the numerator and the denominator.
