Question

Solve the inequality 7(x - 2) < -5.
x < 9/7
x > 9/7
x < -9/7
x > -9/7

Answer 1

ideas ?

Answer 2

\[7(x - 2) < -5\]
\[x - 2 < -\frac{5}{7}\]
\[x < 1\frac{2}{7}\]

Answer 3

Kira - why not 7x-14<-5
7x<9
x<9/7 - i think hence is more easy

- opinion ?

Answer 4

\(\Large \color{blue}{x - 2 < {-5 \over 7} }\)
\(\Large \color{blue}{x < {-5 \over 7} + 2 }\)
\(\Large \color{blue}{x < {-5 \over 7} + {14 \over 7} }\)
\(\Large \color{blue}{x < {9 \over 7} }\)

Can you solve the questions that are left? This one was tough so I did it for you.

Answer 5

I think it's the same... So yeah... Because I prefer to remove coefficient of x then work with it.
