18-28x=31
Swap sides so that all variable terms are on the left hand side.
-28x=31-18
Subtract 18 from both sides.
-28x=13
Subtract 18 from 31 to get 13.
x=\frac{13}{-28}
Divide both sides by -28.
x=-\frac{13}{28}
Fraction \frac{13}{-28} can be rewritten as -\frac{13}{28} by extracting the negative sign.
