-2/3u+7 > 7u-9

3*(-2/3u)+3*7 > 3*7u-3*9

-2u+21 > 21u-27

-2u-21u > -27-21

-23u > -48

u < -48/(-23)

u < 48/23

Solve the inequality for u
First get u on its own side and the integers on their own side by doing the inverse of the variables and the intergers. Then divide the u value by the interger on the other side.
-2/3u+7>7u-9
+2/3u. +2/3u
7>7.666666667u-9
+9. +9
16>7.666666667u
2.086956522>u
Math Frac enter= 48/23
