9x-7i > 3(3x-7u)
9x - 7i > 3 (3x -7u)
= 9x - 7i > 9x - 21u
= -7i > -21u
= ?
I did all the work for you. All you have to do is simplify.
Hint: When dividing both sides by a negative, the sign flips. c:
Good luck.

(4/2) (60+9) - (6969+130 )= D - 6969
(2x69) - 7099 = D - 6969
138 - 7099 = D - 6969
-6961 = D - 6969
-6961+ 6969 = D
? = ?
Again, all the work is done for you.
This one's pretty straightforward.
