Question

solve the inequality and graph its solution:
–7 < 2s + 5 < 15

Answer 1

\(\normalsize\color{blue}{ –7 < 2s + 5 < 15 }\)
\(\normalsize\color{blue}{ –7\color{red}{-5} < 2s + 5\color{red}{-5} < 15\color{red}{-5} }\)
\(\normalsize\color{blue}{ –12 < 2s < 10 }\)
\(\normalsize\color{blue}{ –12 \color{red}{\div 2}< 2s \color{red}{\div 2}< 10\color{red}{\div 2} }\)
\(\normalsize\color{blue}{ –6 < s < 5 }\)
