Question

Solve

9x - 7i < 3 (3x -7u)

Answer 1

please what is the meaning of \(i\) and \(u\) ?

Answer 2

uh... I dunno

Answer 3

hint:
if we apply the distributive property of multiplication at the right side, we get:
\[\Large 9x - 7i = 9x - 21u\]

Answer 4

oh wait I got it my friend just helped me

Answer 5

oops.. I have made a typo:
\[\huge 9x - 7i < 9x - 21u\]

Answer 6

can you check tho

Answer 7

if we subtract \(9x\) from both sides, we can write this:
\[\Large \begin{gathered}
9x - 7i - 9x < 9x - 21u - 9x \hfill \\
\hfill \\
- 7i < - 21u \hfill \\
\end{gathered} \]

Answer 8

as we can see, if I have no conditions on \(u\) and \(i\), I'm not able to say anything

Answer 9

ohh

Answer 10

So then its i <3 u right?

Answer 11

Thank you!

Answer 12

please, from last inequality, we can write this:
\[\huge i > 3u\]
