janetfizz said:thank you very much how do you do 5p-7=18 and y-14.4< 18.39
pka said:You have not given a very clear statement of your problem!
Depending of which it means:
\(\displaystyle \begin{array}{l}
\frac{1}{{3x}} < 21\quad \Rightarrow \quad \frac{1}{{63}} < x \\
\frac{1}{3}x < 21\quad \Rightarrow \quad x < 63 \\
\end{array}\)
Please learn to format the question you mean to ask!
