Question

2 |2x-7| +11 <= 25

Answer 1

\[2 |2x-7| +11 \le 25\]

Answer 2

First isolate the \(|2x-7|\) part, can you do that?

Answer 3

isolate?

Answer 4

Okay so let \(y=|2x-7|\). Substitute it. \[
2y+11\leq 25
\]Would you be able to solve for \(y\)?

Answer 5

i guess so.. i'll just transpose 11?

Answer 6

where did 2x go?

Answer 7

Ummm, just try to get \(y\) by itself.

Answer 8

Well I said \(y=|2x-7|\), so we are ignoring \(x\) for now.

Answer 9

Ignore everything and just solve for \(y\) here. \[
2y+11\leq 25
\]

Answer 10

\[
2\color{red}{|2x-7|}+11\leq 25 \to 2\color{red}y+11\leq 25
\]

Answer 11

ohh.. i see.

Answer 12

Okay can you at least isolate \(y\)?

Answer 13

can i do it later? i need to take my lunch
