u+9-4u>2
Subtract 4u from both sides.
-3u+9>2
Combine u and -4u to get -3u.
-3u>2-9
Subtract 9 from both sides.
-3u>-7
Subtract 9 from 2 to get -7.
u<\frac{-7}{-3}
Divide both sides by -3. Since -3 is negative, the inequality direction is changed.
u<\frac{7}{3}
Fraction \frac{-7}{-3} can be simplified to \frac{7}{3} by removing the negative sign from both the numerator and the denominator.
